Method and optical system for obtaining tomographic distribution of wavefront of electromagnetic field

摘要

The invention comprises a step of measuring a distribution function of light intensity in at least two images at different optical planes having optical path differences (101, 102), a wavefront (104) of light used in the optical system (100). And a method for two-dimensionally reproducing. In particular, the method is suitable for examining the tomographic distribution of the wavefront of the electromagnetic field with an image detector (eg, any standard two-dimensional camera).
