基于折射式棱锥波前传感器，结合二元光学原理，设计一种衍射式棱锥波前传感器。对衍射式棱锥的波前探测原理进行了理论推导，计算了单项 Zernike 像差通过两种波前传感器后四个子光瞳像的光强分布，对两种器件对不同像差的平均斜率测量精度和光能利用率做了定量计算和比较。计算结果证明衍射式棱锥器件可以对波前像差进行有效探测，构建微型人眼波前像差测量系统。

A kind of diffractive pyramid wavefront sensor for the measurement of wavefront aberration is designed based on the refractive pyramid wavefront sensor and the binary optical principle. The theoretical derivation of diffractive pyramid wavefront detection is made and the intensity distribution of the four sub-pupil image for the single term Zernike aberration through the two wavefront sensor is calculated. The average slope of the two devices on different aberration and energy utilization quantitative is quantitatively calculated and compared. The calculation results show that the diffractive pyramid wavefront sensor is capable of detecting the wavefront aberrations effectively and it can build miniature measurement system of human-eye wavefront aberration.
