Title: Method and apparatus for generating and detecting ultrasonic waves in sample
Inventor: MATSUMOTO TAKAHIRO
IPC: G01N21/00
Filed: 1990-11-14
Abstract: PURPOSE:To increase the ultrasonic intensity in a simple constitution to enable high- sensitivity detection by directly applying a laser modulated light to a sample to generate ultrasonic resonance in the sample to be detected as an electric signal through a light interferometer and a photo detector and so on. CONSTITUTION:When continuous laser modulated light is directly applied to a sample 25 by a resonance ultrasonic wave generating laser 21, a light modulator 23, a chopper 24 and so on, the ultrasonic resonance corresponding to the elastic modulus is generated in the sample 25 by thermal stress, so that the surface of the sample 25 is vibrated. Thus, the frequency of a detecting laser light from a resonance ultrasonic wave detecting laser 22 is shifted, Doppler-shifted interference laser light is detected by a Fabry-Perot interferometer 31, and the resonance ultrasonic wave is detected as an electric signal by a photo detector 33 and a by-pass filter. The chopper 24 is feedback-controlled through a lock-in amplifier 36. Even at the time of high temperature, the ultrasonic intensity can be detected at good S/N ratio with high sensitivity without the evaporative reaction force in a simple constitution for narrow band detection. A burst pulse is directly applied instead of a laser modulated light to exhibit the same effect.
