To measure low frequency small displacement vibration, a non- contact sensor based on the optical feedback effect in a laser diode is developed. The principle and experiment setup are described. The optical laser diode power vibration is processed to measure the low-frequency small-amplitude vibration generated by a buzzer. Clinical experiments are proceeded. Three subjects are measured on their flexor digitorum muscle belly with the optical probe. Experimental results are analyzed with fast Fourier transform.
