Multichannel interferometric demodulator

This paper outlines recent progress made by Optiphase Inc.in the development of low-cost, high performance interferometric demodulators applied to multi-channel interrogation. The paper's focus is on the Optiphase digital demodulation concept applied first for single channel operation and then to multi-channel operation. This paper also presents single and multi-channel demodulation test data taken from hardware developed for these applications.
