摘要
高速线扫描共焦检眼镜使用线光束照明眼底视网膜,同时利用线阵CCD对视网膜平面的单次散射线光束探测成像。系统光学放大率为7倍,横向分辨率小于10 μm,对于58 kHz线频的1024 pixel×512 pixel成像模式,成像帧频高达110 frame/s。该系统实现了高分辨率、高帧频模拟人眼实验图像的获取。
Abstract
High-speed line scanning confocal laser ophthalmoscope (LSO) uses a line beam to illuminate the retina, meanwhile a linear array CCD is used for imaging the retina. The magnification of the optical system is about 7 times, and the transverse resolution is less than 10 μm. For 1024 pixel×512 pixel imaging mode (the sensor line frequency is 58 kHz), the frame frequency can achieve 110 frame/s. Therefore, images of an artificial human eye with high resolution and high frame frequency are achieved by the developed system.
