Description

Many important applications for photorefractive crystals (PRCs) have been found recently by various investigators [1–3]. These applications range from volumetric information storage in optical computing to adaptive, remote detection of ultrasonic vibration in optical nondestructive evaluation [4]. In this paper, we propose the use of PRCs for lock-in detection of continuously vibrating structures.

Optical Lock-in Vibration Detection Using Photorefractive Four-Wave Mixing
