摘　　要：医用内窥镜的入瞳视场角是一个关系到内窥镜临床应用的重要指标,同时也直接影响了其他相关光学参数的测试准确性,现有标准中均未提及矩形视场下的测试方法。为了完善医用内窥镜的测试体系,本文从几何光学原理出发构造了入瞳视场角的简化几何模型,建立了医用内窥镜矩形视场下入瞳视场角的测试方法,为矩形视场下内窥镜入瞳视场角的客观测量和评价提供了必要的参考。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.
