Two-dimensional image processing using two channels formed by one acousto-optical filter
Properties of a two-channel acousto-optic (AO) spatial frequency filter deflecting optical beams in two symmetrical orders are studied. It is found that the non-uniform distribution of the field in each order makes it possible to process images in two channels using different transfer functions. The...

| description | Properties of a two-channel acousto-optic (AO) spatial frequency filter deflecting optical beams in two symmetrical orders are studied. It is found that the non-uniform distribution of the field in each order makes it possible to process images in two channels using different transfer functions. The formation of a two-dimensional contour in two diffraction orders is confirmed ex-perimentally on the basis of image processing for a wavelength of 0.63 μm. A TeO 2 AO cell oper-ating at an acoustic frequency of 26 MHz is used as a two-channel spatial frequency filter. |
