The research of medical endoscope field of view and direction of view testing method

According to endoscope Field of View (FOV) and Direction of View (DOV) features, This paper has improved the traditional testing method by rotating testing target. At the same time, analysed the theory of vertex field angle and object pupil field angle, and the paper has given the mutual transformation relationship between the two, which provided a theoretical basis for the simplified endoscopic detection method.
