ABSTRACT:
A holographic endoscope transmits light to an object and receives and transmits the image of that object. The light transmitted is used to illuminate an object with one of two beams which are derived from a single laser, while the image received is transmitted from the object. The light from the image transmitted passes through a field lens, and a second beam or reference beam is made to interfere with this light. The resulting interference pattern is recorded on a photographic plate, forming the hologram.
