摘要

Feedback phenomenon in laser diodes is applied to low-frequency vibration measurement in the micrometer range on poorly reflecting targets. The laser diode is frequency modulated. Its beam is focused on the vibrating target, and backscattered light is fed back into the laser. The optical laser diode power variation is processed to measure the frequency and amplitude of low-frequency vibrations of amplitude, similar to 100 nm to 10 mu m. Experimental results for sinusoidal and triangular vibrations are compared with theory. (C) 1997 Optical Society of America.
