Abstract
In this paper, the implementation and the characterization of this multichannel photorefractive ultrasonic sensor is presented. The multichannel photorefractive ultrasonic sensor uses single photorefractive crystal and a linear matrix photodetector. The characterization is based on the presence of possible cross-talk between the channels. And different possible configurations for the wave-mixing in the photorefractive crystal are also studied.
