METHOD FOR MEASURING THE WAVE FRONT MODES OF LIGHT WAVE BY HOLOGRAPHIC WAVE FRONT MODE SENSOR AND DEVICE FOR IMPLEMENTING THE METHOD

摘要

FIELD: optical instrumentation. ;SUBSTANCE: invention relates to the field of optical instrumentation and concerns a method for measuring the Zernike wave front modes by a holographic wave front mode sensor. The mode measurement method contains an iterative process that involves increasing the diameter of the measured wave front, from a diameter value significantly smaller than the maximum diameter of the measured wave front to a value equal to the maximum diameter of the measured wave front. The method includes measuring the amplitude of the wave front modes at different values of the wave front diameter and reducing the wave front aberrations in each iterative cycle with a wave front corrector. ;EFFECT: increased measurement speed and the number of measured Zernike wave front modes.;3 cl, 6 dwg, 2 tbl
