Abstract
A fibre optic device which can be used as an endoscopic probe for medical or engineering applications comprises an optical fibre having at least one electroluminescent device provided at the distal end of the optical fibre for illumination purposes. The electroluminescent device comprises at least one layer 6 of an electroluminescent material such as an electroluminescent polymer located between first and second electrodes 4, 8 and located at the distal end of optic fibre such that charge carriers can move between each of the first and second electrodes and thereby illuminate the electroluminescent material. Insulating layer 12 is located between the two electrodes at the proximal end of the device. First electrode 4 can be opaque or reflective to stop light entering directly into fibre optic core 2 and second electrode 8 and protective coating 10 can be transparent to allow the light to shine through.
Description
2356464 FIBRE OPTIC DEVICE The present invention relates to a fibre optic
device, and in particular to an endoscopic probe for use in surgical examination or keyhole surgery or a probe for use in engineering applications such as chamber defect detection or static sampling methods such as in stream spectroscopy.
A conventional optical fibre probe comprises at least one optical fibre for directing light from an external light source to illuminate the subject of interest, and at least one second fibre for receiving light reflected from the subject of interest. The requirement for two optical fibres results in a relatively bulky probe which in turn necessitates a relatively large entry aperture.
Furthermore, an optical fibre provides an intense point light source which only illuminates a relatively small area resulting in a narrow field of view. There is known a technique for delivering an increased field of view which comprises roughening the tip of the optical fibre which delivers the light. However, the viewing angle is still relatively restricted.
It is an aim of the present invention to provide a fibre optic device which at least partially overcomes the above-mentioned problems of conventional probes.
According to the present invention, there is provided a fibre optic device comprising: an optical fibre having a distal end and a proximal end; and at least one e 1 ectrolumines cent device provided at the distal end of the optical fibre, the electroluminescent device comprising at least one layer of an e 1 ectrolumines cent material located between first and second electrodes such that charge carriers can move between each of the first and second electrodes and the electroluminescent material.
The provision of an electroluminescent device at the distal end of an optical fibre has the advantage that a single fibre can be used for simultaneously illuminating the subject of interest and receiving light reflected from the subject of interest. A reduction in the size of the probe as a whole is thereby made possible allowing access to smaller cavities.
Furthermore, by providing the light source as an electrolumine scent device on the circumferential surface of the distal end of the optical fibre, there is created the possibility of illuminating a larger area under more diffuse light than with conventional probes.
Hereunder, an embodiment of the present invention will be described with reference to the accompanying drawings, in which:- Figure 1 shows a schematic longitudinal cross-sectional view of the distal end of a probe according to an embodiment of the present invention; Figure 2 shows a schematic radial cross-sectional view of the distal end of the probe shown in Figure 1, as take n through line A-A in Figure 1; and 2 Figure 3 shows a schematic radial cross-sectional view of a portion of the probe shown in Figure 1 remote from the distal end, as taken through line B-B of Figure I..
With reference to Figures 1 to 3, the radial surface of the portion of an optical fibre which is intended to be inserted into a human or animal body or an apparatus is coated with a first electrically conductive layer 4 about the entire circumference of the fibre. At the distal end of the optical fibre, a layer of an elect rolumine scent material 6 is coated on the surface of the first conductive layer 4 about its entire circumference. The remaining area of the surface of the first conducting layer 4 is coated with an electrically insulating layer 12 about its entire circumference. A second electrically conductive layer 8 is then provided on the outer surface of the layer of electroluminescent material 6 and the electrically insulating layer 12. Finally the outer surface of the resulting coated fibre is provided with a protective transparent coating 10.
At the distal end of the probe, the- combination of coatings described above provides an elect rolumine scent device comprising a layer of electrolumines cent material 6 located between two electrodes 4, 8.
The first conductive layer 4 is preferably opaque and/or reflective to prevent the transmission of light emitted from the elect roluminescent material during operation of the device directly into the optical fibre via the first conductive layer 4, which direct input of light would undesirably dominate the total intensity of light transmitted back down the optical fibre.
3 Suitable materials for the first conductive layer 4 include low work function materials, for example metals such as calcium, lithium etc.. In a preferred embodiment, the portion of the first conductive layer adjacent the electroluminescent layer has a bi-layer construction comprising a relatively thick layer of a metal such as silver or aluminium followed by a relatively thin layer of a metal comprising a low work function element adjacent the electrolumine scent layer such as a layer of calcium or lithium or a metal salt such as lithium fluoride.
According to an alternative embodiment, the first conducting layer 4 can be replaced by a two-layer coating comprising an opaque and/or reflective layer (which does not need to be electrically conducting) and an electrically conductive layer adjacent the electroluminescent layer 6. This alternative embodiment has the advantage that the conductive layer adjacent the elect rolumine scent material can be selected with a view to optimising its performance as an electrode in the electroluminescent device without needing to be concerned about its light transmission properties, and, likewise, the opaque and/or reflective layer can be selected with a view to optimising its light blocking properties without needing to be concerned about its performance as an electrode. For example, the opaque and/or reflective layer could be a layer of a dyeloaded polymeric materials applied from paints, powder coating or directly from a melt. The conductive layer located between the opaque and/or reflective layer and the electroluminescent layer may, for example, have the single layer or bi-layer construction des cribed above.
4 The elect rolumine scent layer is preferably a layer of a fully or partially conjugated polymer. Suitable materials include one or more of the following in any combination: poly(p-phenylenevinylene) ("PPV"), poly(2-methoy-5(21ethyl) hexyloxyphenylenevinylene ("MEH-PPV"), one or more PPV-derivatives (e.g. di-alkoxy or di-alkyl derivatives), polyfluorenes and/or co-polymers incorporating polyfluorene segments, PPVs and related co-polymers, poly(2,7-(9,9-di-n-octylfluorene)-(1,4phenylene-((4- secbutylphenyl)imino)-l,4-phenylene)) ("TFB"), poly(2,7(9,9-di-n- octylfluorene)-(1,4-phenylene-((4methylphenyl)imino)-1,4-phenylene))(4- methylphenyl)imino)-1,4-phenylene)) ("PFM/'),, poly(2,7 (9,9-di-n-octylfluorene)-(1,4-phenylene-((4methoxyphenyl)imino)-1,4-phenylene-((4methoxyphenyl)imino)-1,4-phenylene)) ("EIFMO"), poly(2,7 (9,9-di-n-octylfluorene) (" F8 ") or (2, 7- (9, 9-di-noctylfluorene)-3,6-benzothiadiazole) ("HBT").
Alternative materials include small molecule materials such as Alq3.
According to an alternative embodiment, the el ectrolumine scent layer may be used in conjunction with further electroluminescent layers and/or charge carrier transport layers such as electron transport layers and hole transport layers provided between the two electrodes.
The second conductive layer 8 is preferably transparent, so that any light emitted from the electroluminescent layer 6 during operation can also be transmitted therethrough thereby providing a larger window via which the light can reach the subject of interest. it preferably comprises a high work function material such as indium tin oxide or a platinum group metal.
The portion of the second conducting layer 8 which is formed on the electrically insulating layer 12 does not need to be made of the same material as the portion of the second conducting layer 8 formed on the layer of electroluminescent material 6. For example, the portion of the second conducting layer 8 on the electrically insulating layer 12 could be opaque and the portion of the second conducting layer 8 on the el ectrolumine scent layer 6 could be transparent.
Suitable materials for the electrically insulating layer 12 include, for example, cyanoacrylates and epoxy resins. Epoxy resins are preferred.
The transparent protective coating 10 serves to protect the electroluminescent device from being damaged. it preferably comprises an electrically insulating material such as, for example, a cyanoacrylate or, preferably, an epoxy resin.
The optimal thicknesses of each of the layers comprising the electrolumines cent device can be determined by the person skilled in the art. As will be apparent to the skilled person, it is preferable to reduce the total thickness of the electroluminescent device as much as possible without substantially compromising the performance of the electroluminescent device, in order to reduce the diameter of the probe as a whole. Preferred thicknesses for each of the layers are as follows. The first conducting layer preferably has a thickness of about 100nm or greater, further preferably between 400 6 and 1000nm; when the region of the first conducting layer adjacent the e 1 ectrolumines cent layer is provid ed with an additional layer comprising a low work function element (such as calcium) as discussed above, the thickness of such additional layer is preferably about 10nm or greater, further preferably between 10 and 50nm. The thickness of the electroluminescent layer is preferably in the range of 50 to 100nm, further preferably in the range of 60 to 80nm. The thickness of the second conducting layer will depend largely on the type of material when it is required to be optically transparent as in a preferred embodiment. In such an embodiment, the thickness of the second conducting layer has to be sufficiently thin that the layer remains optically transparent. In the case that indium tin oxide is used for the second conducting layer, the thickness is preferably about 150nm.
In the probe shown in Figure 1, the diameter of the probe is the same for both the portion thereof having the electroluminescent device provided thereon and the portion thereof having the two conducting layers 4,8 separated by the electrically insulating layer. However, the diameter of the probe does not have to be uniform along the entire length thereof, but it is preferred that any variation in diameter is as smooth as possible to try and avoid the probe from becoming caught when being removed from the patient's body or apparatus under inspection.
Furthermore, the probe shown in Figure 1 and described above has the electroluminescent device provided right at the distal end of the optical fiber i.e. adjacent the tip of the distal end of the optical fiber. Alternatively, 7 the elect rolumine scent device can be spaced from the tip of the distal end of the optical fiber.
In operation of the probe, a potential difference is created across the first conductive layer 4 and the second conductive layer 8 at the proximal end of the optical fiber 2 by means of a suitable power source to create a potential difference across the electroluminescent layer 6 sufficient to cause the electrolumine scent layer 6 to emit light of the required intensity. When the portion of the second conductive layer 8 on the electroluminescent layer 6 is transparent, the light emitted by the elect rolumine scent layer 6 is primarily transmitted radially from the distal end of the optical fiber 2. This radial transmission of light from the distal end of the optical fiber permits the illumination of a relatively large area under relatively diffuse light. Light reflected from the subject of interest illuminated in this way is received in the core of the optical fiber and is guided to the proximal end of the optical fiber to which is generally attached a device for converting the light reaching the proximal end of the fiber into an image for viewing.
