Abstract
A stereoscopic endoscope employing a single light sensor array and a lenticular lens layer located at a proximal end of the endoscope, a pair of periscopic prisms located at a distal end of the endoscope and an optical relay assembly array located between the pair of periscopic prisms and the light sensor array. One prism of the pair of periscopic prisms receives a right view of an object and another prism of the pair receives a left view of the object. The interpupilar distance (IPD) between the right and left view is substantially large, thereby increasing the resolution of a stereoscopic image which is eventually displayed on a display. Another embodiment includes a set of three light sensor arrays, a light director and three lenticular lens layers. Each light sensor array detects light at a predetermined range of wavelengths (e.g. red, green and blue).
