Paper Abstract

Image modulation of an acoustic wave produces refractive effects in a volume of elasto-optic material. A plate having the thickness of half the acoustic wave length generates refractive patterns corresponding to the phase and amplitude modulation of the acoustic carrier. From this a method is proposed to obtain realtime images from sonar echoes. A laser interferometer is described by which the phase undulation of the echo wave front may be encoded in video format. Realtime image reconstruction techniques are presented. Applications and limitations of acoustic imaging are discussed.
