The present invention relates to a variable shear rate wavefront sensor based on random coded hybrid grating, mainly involving the field of optical wavefront detection and quantitative phase detection.
Transverse shear interference technology uses the wavefront itself to carry out dislocation interference, so as to achieve direct measurement of the phase of the wave front
The four-wave transverse shear interference wavefront detection system based on random coded mixed grating is mainly composed of random coded mixed grating and CCD
