Abstract:
The problem of calculation of acousto-optic filter characteristics with control of the number of volumetric diffraction gratings and their structure is taken into consideration. Special-case calculation methods are described including those in collinear geometry. It is demonstrated that there is an approach allowing to perform detailed calculation of spectral characteristics in wide-aperture diffraction geometry used for problems of spectral analysis of object images. It allows to divide the entire luminous flux into separate beams with the partial transmission function of each of them being described by a simple path integral. This method allows for determining the impact of acoustic wave modulation on the filter spectral transmission function.
