Abstract

An adaptive method for wavefront aberrations compensating has been developed based on the use of a spatial light modulator, the phase function of which is matched to a set of Zernike functions. It is proposed to use the second central moment of intensity of the focal image as a functional. A study of the second central moment was carried out for both individual wavefront aberrations and their superposition. It is shown that achieving the reference value of the second moment can serve as a sign of sufficient compensation for aberration.

基于矩量法的波前像差自适应补偿

提出了一种基于空间光调制器的波前像差自适应补偿方法，该方法的相位函数与一组Zernike函数相匹配。提出了利用焦像强度的第二中心矩作为函数。对单个波前像差及其叠加进行了二次中心矩的研究。结果表明，达到二阶矩的参考值可以作为充分补偿像差的标志。
