METHOD OF RECORDING OPTICAL WAVE FRONT AND SYSTEM TO THIS END Russian patent published in 2011 - IPC G01J9/00 G02B27/44 

FIELD: physics.

SUBSTANCE: monochromatic acoustic wave is excited in optical-acoustic cell made from optically anisotropic crystal that allows Bragg's optical-acoustic diffraction with dissipation of light radiation at simultaneous to diffraction peaks of +1-th and -1-th orders. Then, spatially-modulated coherent light wave that carry analysed image is passed through said cell. At the same time light wave is dissipated through two Braggs' peaks of +1-th and -1-th orders. Images formed in said diffraction peaks are separately recorded by means of two matrix photo cells and their output signals are analysed in electronic unit. Two electric signals with separated data on amplitude and phase structure of analysed image are generated to display visible images of amplitude and phase structure on monitor.

EFFECT: simultaneous analysis of amplitude and phase structure of optical field.
