Paper Abstract

This paper critically analyzes a new open loop interferometric demodulation technique which utilizes digital processing approaches to achieve a direct optical phase measurement. This approach is compared to traditional FM discrimination approaches which are currently used for interferometric demodulation. The comparisons include intrinsic performance capabilities and measurement errors resulting from imperfect interferometric sensor conditions.
