abstract

The linear phase demodulation of a signal from the detector of an interferometer, subjected to alternating elongation for large dynamic range crossing a number of fringes, with low power signal processing has been implemented using different schemes. These include phase generated carrier homodyne demodulation (PCHD), pseudo-heterodyne and finally a power optimized phase tracker.
