为了获得人眼眼底高分辨率图像,将液晶自适应光学(AO)技术引入到传统检眼镜中。采用基于夏克-哈特曼波前探测器(SHWS)和硅基液晶空间光调制器(LCOS-SLM)的自适应光学系统来校正人眼的高低阶像差,获得了细胞量级的高分辨眼底图像,为眼科疾病及其相关疾病的早期诊断提供了有力工具。采用闭环和开环两种校正模式,都获得了清晰的眼底图片,认为液晶自适应光学系统在活体人眼眼底高分辨率成像上具有巨大潜力。
In order to obtain a high-resolution image of the human eye, liquid crystal adaptive optics (AO) technology is introduced into conventional ophthalmoscopes. The high and low order aberrations of the human eye were corrected using an adaptive optics system based on the Shack-Hartmann wavefront detector (SHWS) and the liquid-crystal spatial light modulator (LCOS-SLM) Identify the fundus images, and provide a powerful tool for the early diagnosis of eye diseases and their related diseases. Using both closed-loop and open-loop calibration modes, clear images of the fundus have been obtained, suggesting that the liquid crystal adaptive optics has great potential for high-resolution imaging of the living human eye.
