旋转点扩展函数（PSF）提供了一种新的三维位置检测方法。由于系统的光学像差难以完全消除，本文从解析和数值两方面研究了像差对PSF的影响。结果表明，光强模式对像散和彗差都有较强的鲁棒性，而像散影响点光阑的旋转角度，彗差影响点光阑的横向位置。
Rotating point spread function (PSF) provides a novel approach to detect three-dimensional position. As the optical aberration of a system can hardly be removed completely, effects of aberration on the PSF were studied both analytically and numerically. Results show that the intensity pattern is robust to both astigmatism and coma, while astigmatism affects the rotating angle of the PSF, and coma affects the lateral position of the PSF.
