Abstract

We present the multichannel fiber-optical system for detection and reconstruction of weak acoustic field. Developed system is based on 32-channel adaptive holographic interferometer that employs multiplexing of dynamic holograms in a single photorefractive crystal of CdTe. The multichannel fiber-optical sensory system was tested for registration and spatial reconstruction of acoustic field created in a solid plate.
