Paper Abstract

The acousto-optic method of phase object visualization is generalized to the case when an optical wave as well as being spatially phase-modulated, has also amplitude spatial modulation. A special geometry of acousto-optic interaction is proposed for separation of the phase modulation and visualization of the optical wavefront. Basic characteristics of the visualizing system are calculated. It is shown that in the optimal case the distribution of light intensity in the visualized image is proportional to the phase gradient in the acousto-optic interaction plane. The resolution and the contrast of the visualized image are determined primarily by the divergence angle of the acoustic beam. Some examples of computer simulation are presented for illustration of potentialities of this method.
