Development of optical performance calibration device for electronic target medical rigid endoscope
An electronic target type optical performance calibration device for medical rigid endoscope is proposed.The device is composed of a special OLED display screen,a special 4K HD adapter lens,an imaging and image acquisition CMOS system,an image processing computer,an electrically controlled linear guide and angle encoder,an integrated light effect detection system,and software modules.Using the high-resolution and high refresh rate characteristics of OLED display,we can analyze many optical parameters such as field angle,direction angle,geometric distortion,and optical transfer function of medical rigid endoscope at the calibration customer's site.
