Abstract

Abstract

The character of optical back reflection and optical transmission through confocal Fabry-perot interferometer is analyzed, and a method of laser ultrasound conjugate detection using interferometer is demonstrated. The experimental results is given. This method can enhance the detection sensitivity of laser ultrasound detection system at least two times.
