Abstract
The technique described uses Brillouin scattering from microwave sound at the Bragg angle to achieve cross correlation. Spatially coherent light waves are phase-shifted in the spatial domain by a phase-modulated pulse train in an acoustic delay cell. These modulated light waves are, in turn, multiplied by a phase plate to produce the desired convolution.Keywords
