摘要
针对目前人眼像差哈特曼夏克测量仪不能自动补偿人眼离焦的不足, 通过分析不同调焦状态下连续采集的哈特曼夏克光斑图像序列, 构造了离焦补偿评价函数, 在现有像差测量仪平台上实现了人眼像差自动离焦补偿。算法根据调焦过程中哈特曼夏克光斑的形态变化, 定义了通过光斑图像评估离焦补偿结果的评价标准, 并依据评价函数确定最佳光斑图像对应的离焦补偿量, 从而确保哈特曼夏克波前传感器能准确测得离焦补偿后剩余的人眼像差。实验结果表明, 本方法对杂散光噪声具有较强的稳健性, 可以准确实现调焦系统的自动离焦补偿, 为后续像差测量仪精密测量人眼高阶像差提供了十分重要的方法。
Abstract
An automatic defocus compensation method for human eye Hartmann-Shark (HS) wave-front aberrometer is proposed. According to the analysis of different geometric features of HS light spots during focalizing process, estimation algorithm is constructed to remove large-scale defocus amount, and then the residual high-order ocular aberrations can be measured by aberrometer successfully. Experimental results proved that the method has good robustness to control noise and can achieve accurate automatic defocus compensation from ocular aberrations, which is very useful method to human eye HS wave-front aberrometer.
