Abstract

Novel concepts for simplification of the optical design of a time-integrating acousto-optical signal processor for real-time Fourier transformation are described. Fourier transforms of both pulsed and continuous signals, obtained from the triangular common-path interferometric setup, are demonstrated. Because of their simplicity, these concepts are suitable for designing ultracompact devices.
