摘要
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。
Abstract
In order to obtain human eye fundus images with high spatial resolution,the liquid crystal (LC) adaptive optics (AO) systems was introduced to the traditional ophthalmoscopes. The AO system based on Shark-Hartmann wavefront sensor (SHWS) and liquid-crystal-on-silicon spatial light modulator(LCOS-SLM) could detect and correct the low and high orders eye′s aberrations,and obtain the human eye fundus images with high spatial resolution. It is a useful tool for early diagnosing the eye diseases and diseases interrelated to the eye. The open-loop and closed-loop mode were both adopted. They could both obtain human eye fundus images with high spatial resolution. The LC-AO system possesses a great potential in human eye fundus imaging with high spatial resolution.
