摘要
提出一种电子靶标式医用硬性内窥镜光学性能校准装置.该装置由专用电子靶标显示屏,专用高清摄像镜头、视频图像采集系统、数字图像处理计算机、多维度调整台及角度编码器和软件模块组成.可在校准客户现场分析医用硬性内窥镜视场角、视向角、几何畸变和光学传递函数等多项光学参数.
Abstract
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.
