SPACE INTEGRATING INTERFEROMETRIC ACOUSTOOPTIC CONVOLVER

A coherent space integrating convolver using image inversion optics is introduced that provides both high system stability and high output d ynamic range with the minimum required output covolution signal tempor al and spatial frequency offsets. Test autoconvolutions are generated by the system for amplitude modulated (AM) input signals using a 100 M Hz carrier with a 13 MHz modulation, producing the desired time compre ssed offset carrier-free 26 MHz autoconvolution output with a dynamic range of 47.2 dB measured in a 30 KHz analyzer resolution bandwidth.
