| Abstract: | A confocal Fabry Perot interferometer for an ultrasonic receiver is developed. We discusse the principle of detecting ultrasonic waves using this kind of interferometer, give the foundation of determining parameters of the interferometer and practical structure, evaluate the confocal difference needed for following experiments and obtain the interference pattern and transimission intensity curve. Finally, this interferometer is successfully applied to detecting ultrasonic pulses in metals generated by laser pulse. |
