Abstract：The object pupil field angle of the medical endoscope is an important parameter related to clinical application of medical
endoscope, and it also directly determines the accuracy of other related optical parameters. Until now, there is no related test method
of the object pupil field angel under the rectangular field of view in the existing standards. In order to improve and complete the test
system of medical endoscope, we constructed a simplified geometric model of the object pupil field angle on the basis of the principle
of geometrical optics, and established the test method of the object pupil field angle of the medical endoscope under the rectangular
field of view. The test method proposed here provides a reference for the objective measurement and evaluation of the object pupil
field angle of medical endoscope under the rectangular field of view.
