Abstract
The present optical apparatus for measuring properties of a material comprises an ultrasonic exciting source for generating a pulse beam, a stand for loading a sample, an optical ultrasonic detector, a waveform recorder, and a processor. The ultrasonic exciting source includes a laser source and focusing lens for narrowing the spot size of the pulse beam. The optical ultrasonic detector uses the interferometry technology to detect a surface acoustic wave generated by the irradiation of the pulse beam on the same, the waveform recorder recodes the surface acoustic wave, and the processor calculates the property of the sample based on the surface acoustic wave.
