Abstract

We built and tested a novel in-line interferometric time integrating acousto-optic correlation which has distinct advantages over existing designs. The novel design demonstrates improved vibrational stability, system light efficiency and dynamic range over the dual-path Mach- Zehnder interferometric correlator. The design also provides a tunable spatial frequency at the detector, unlike the non-interferometric in-line correlator which has a fixed spatial frequency.
