摘要：

A time-integrating optical processor is configured for one-dimensional chirp correlation spectrum analysis. A unique optical implementation, utilizing TeO//2 shear wave acoustooptic cells, is designed to operate in a configuration which allows wide bandwidth diffraction to 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.
