Abstract
In this work, a possible new PD detection technique, based on the Michelson Interferometer, has been proposed. Laser beam transmitted by optical fiber is spliced into two-laser beam by 50/50 coupler, one is reflected on diaphragm, which is vibrated by ultrasonic sound, and then modulated. The other one is reference beam. They are collected into 50/50 coupler making interferenced beam which could be detected by photo detector.
