Abstract

From a laser (L) is delivered a short pulse, which is divided into an expanded reference beam incident at an angle against a photographic plate (H), and an expanded illumination beam which illuminates a master object (O). The plate is developed to form a holographic image and remounted in the same setting, and a comparison object is brought into the same position as the master object. The plate (H) is illuminated from its opposite side with an expanded short pulse beam antiparallel to the reference beam, light diffracted from the plate image illuminating the comparison object. Light brought back antiparallel relative to the expanded illumination beam is brought to a detector (D), the time spectrum therefrom indicating the degree of likeness between the master object and the comparison object.
