Abstract

We present dynamic range and time delay results for a multichannel acousto-optic (AO) correlator using an in-line interferometric time- integrating architecture. This novel design demonstrates improved performance compared to the dual-path Mach-Zehnder interferometric correlator. The design provides control of the correlation spatial frequency to match that of the detector elements. The simplicity of the design, improved dynamic range, and increased stability make the in-line interferometric time integrating correlator an attractive alternative for applications in radar signal processing and spectrum analysis.
