ABSTRACT:
An improved endoscope comprises an objective including a diffractive optical element juxtaposed to a solid-state imaging element at the distal tip of the endoscope. An inexpensive halogen lamp at the proximal end of the endoscope is employed as the illumination source. A fiber-optic bundle carries light to the distal tip of the endoscope, where diffractive optical elements are provided to disperse light, illuminating the field of view.
