AI Technical Summary
Technical Problem
Existing optical endoscopes are difficult to meet the needs of clinical ultra-high-definition imaging.
Method used
An optical endoscope system including an objective lens group, a relay mirror group and a collimating magnifying glass group is designed. The square light spot of the relay mirror group is amplified through the collimating magnifying glass group to ensure that the light exit angle is consistent with the light incident angle of the imaging lens, and the enlarged light spot size is consistent with the inlet pupil size of the imaging lens.
Benefits of technology
High-resolution ultra-high-definition imaging is achieved, and it can form 7680x4320 pixel ultra-high-definition images on an 8K (7680x4320 pixel) image sensor to meet clinical high-resolution needs.

Abstract
The embodiment of the present invention discloses an 8K ultra-high-definition optical endoscope and imaging system, which relates to the technical field of medical devices and is invented to provide an optical endoscope with higher resolution. The optical endoscope includes: a tube body, an objective lens group and a relay lens group arranged in the tube body, the relay lens group is arranged on the image side of the objective lens group, and a collimating magnifying lens group is arranged on the image side of the relay lens group; wherein the objective lens group is used to image the observed object; the relay lens group relays and transmits the image formed by the objective lens group; the collimating magnifying lens group magnifies the light spot on the image side of the relay lens group into a parallel collimated light spot, so that the light emission angle of the relay lens group is consistent with the light incident angle of the camera lens, and the size of the parallel collimated light spot formed after magnification is consistent with the size of the entrance pupil of the camera lens; the light emission side of the relay lens group is the image side of the relay lens group. The embodiment of the present invention is applicable to the scene of medical examination and surgery through endoscope.
