Abstract
A novel dual-path-endoscope where a multi-function light source produces a first-light and a second-light toward an object. The first-light exhibits first-light-characteristics. The second-light exhibits second-light-characteristics different from the first-light-characteristics. The endoscope includes two light-paths, the disparity there between is larger than zero. Each light-path includes a respective pupil and a respective light-separator coupled with the pupil, transmitting there through one of the first-light and the second-light, associating the first-light and the second-light with a respective light-path. The dual-channel-imager includes two imaging sensors, each associated with a respective light-path and optically coupled with a respective light-separator. Each imaging-sensor exhibits sensitivity to the characteristics of the respective one of the first-light and the second-light. A first imaging-sensor acquires a first-image of the first-light reflected of the object and a second imaging-sensor acquires a second-image of the second-light reflected of the object. The processor processes the acquired images.
