Abstract

A time-integrating optical processor is configured for one-dimensional chirp correlation spectrum analysis. A unique optical implementation, utilizing TeO2 shear wave acousto-optic cells, is designed to operate in a configuration which allows wide bandwidth diffraction to both the positive and negative first diffraction orders. The result is high optical throughput efficiency, excellent fringe visibility, and a coaxial system design. Chirp linearity experiments confirm coherence requirements for chirp transform processors.
