Abstract
A spatial Fourier transform approach is employed to investigate the acoustooptic interaction with cw, profiled sound and an incident light beam. Two coupled differential equations which describe the near Bragg interaction are derived in the spatial frequency domain. Since there is no analytic solution for these coupled equations, a well-known numerical technique, viz., the Range-Kutta method is used to solve the equations. Detailed numerical simulation, involving Fourier transforming the input light beam profile to calculate the spectra of the scattered light beams and, hence, their profiles in space using the inverse transform, are presented.
