Abstract
A new type of stable interferometric fiber optic sensor based on the amplitude modulation (AM) technique is applied to the differential distance measurements. By synthesizing interferograms from two interferometers, output signal shows an AM waveform in the optical frequency domain. By extracting the low frequency interval, the imbalance of optical path differences (OPDs) can be extracted. This unique sensor system is described in detail with some experimental results.
