Abstract

Self-mixing interference in a semiconductor laser is employed for the measurement of ultrasonic vibrations. It has been confirmed by numerical simulations and experiments that there is a linear relation between the vibration amplitude and the amplitude of a signal detected from a self-mixing laser diode (SM-LD) - laser diode subject to optical feedback - for vibration amplitudes less than the half-wavelength of the illuminating tight The proposed method is suitable for constructing compact and inexpensive optical systems for measurement of ultrasonic vibrations.
