An acoustooptic filter relates to operation devices for real-time data processing systems based on acoustooptic element base. The acoustooptic filter with spatial discretization comprises acustooptic interaction medium, device for formation of modulated optical beam, converging lens, extra-axial diaphragm, light divider, piezoelectric converters. The filter promotes device speeding, this provides operation thereof in gigahertz and tetrahertz frequency band. |
