We studied the long-term optical performance of an adaptive optics scanning laser ophthalmoscope that uses a liquid crystal on silicon spatial light modulator to correct ocular aberrations. The system achieved good compensation of aberrations while acquiring images of fine retinal structures, excepting during sudden eye movements. The residual wavefront aberrations collected over several minutes in several situations were statistically analyzed. The mean values of the root-mean-square residual wavefront errors were 23-30 nm, and for around 91-94% of the effective time the errors were below the Marechal criterion for diffraction limited imaging. The ability to axially shift the imaging plane to different retinal depths was also demonstrated.
我们研究了一种自适应光学扫描激光检眼镜的长期光学性能，该检眼镜使用硅基液晶空间光调制器来校正眼像差。除了在眼睛突然运动期间外，该系统在获取精细视网膜结构图像时实现了良好的像差补偿。对在几种情况下几分钟内收集的残余波前像差进行了统计分析。均方根残余波前误差的平均值为23 - 30纳米，在约91 - 94%的有效时间内，误差低于衍射极限成像的马雷夏尔准则。还展示了将成像平面轴向移动到不同视网膜深度的能力。
