Abstract
An ultrasonic pressure sensor and a method of detecting ultrasonic pressure. In one embodiment, the ultrasonic pressure sensor includes: (1) an interferometer having a reference arm and a signal arm that includes a probing fiber, the probing fiber having a reflective coating at a distal end thereof and configured to couple to ultrasonic waves proximate the distal end, the interferometer configured to receive laser light and produce two output beams based on the ultrasonic waves and (2) a photodetector coupled to the interferometer and configured to generate electronic signals based on the two output beams.
