Abstract

In one aspect, the present invention provides a sliding door monitoring system comprising a time-of-flight ranging sensor (10) and a retroreflector (80), wherein the time-of-flight ranging sensor comprises a transmitter of electromagnetic radiation and a receiver of electromagnetic radiation, and the retroreflector is positioned to reflect electromagnetic radiation from the transmitter to the receiver. In another aspect, the present invention also provides a method of monitoring a sliding door in a door opening, wherein the method comprises transmitting electromagnetic radiation across a gap in the door opening, reflecting the electromagnetic radiation from across the gap, receiving the reflected electromagnetic radiation on the same side of the gap as its transmission, measuring a time of flight of the electromagnetic radiation from its transmission to its reception and, optionally,an amount of the reflected electromagnetic radiation, and determining a size of the gap from both the time of flight and the amount of reflected electromagnetic radiation thus measured.
