摘要 对基于Hartmann Shack(H S)原理测量人眼波前像差的掩模技术进行了研究。利用光学系统将液晶显示器(LCD)制成的掩模对应成像在微透镜阵列面,对模拟眼进行测量。设计了针对不同采样密度的H S系统的各类掩模,扩大子孔径内像差测量范围,最大可测像差分别提高到L2/f、2L2/f和4L2/f,解决了光斑溢出和粘连的问题,实现了对大像差人眼的准确测量。 The method for measuring the eye's wavefront aberration with a movable mask, based on the Hartmann-Shack (H-S) principle, has been investigated. The mask is implemented by an LCD and imaged on the lenslet array plane, by which we measure aberrations of an artificial eye. Masks corresponding to H-S systems with different sampling densities are designed and the maximum measurable wavefront aberrations in subapertures are increased to L2/f, 2 L2/f and 4 L2/f separately. The method solves the problem of spot dislocations and contiguities, where spots leave their subapertures, leading to an expansion of the dynamic range of H-S sensors.
