MEASURING THE WAVE ABERRATION IN OPTICAL SYSTEMS BY THE DIGITAL SHADOW METHOD
Annotation
A digital method for quantitative control of wave aberrations in optical systems is proposed. The approach is based on the method of izophotometry and involves transformation of a pair of shadow images into geometric models of shadowgrams of a linear grating using transformation function (including the “wedge” function), and the further processing of the models with specially designed software. The analyzed optical system quality is assessed; wavefront deformation map and characteristics of the system image quality are presented.
