,A Project of Ultrasonic Tomography (“Sonoradiography”),In X-ray radiography there exists a technique, known as tomography, in which a sharp image of . section of the body is obtained by moving the X-ray tube and the photographic plate in opposite directions. Can we not produce a similar, or even better effect with ultrasound?

Optical Information Processing and Acousto-Optics,ence and energy science are emerging as basic fundamentals which may be called the main pillars of the science of the new age; thus, the standpoint of elucidating a given object scientifically is not necessarily a single approach. Rather, these three pillars can offer three entirely different points of view.

Ultrasonic Holography by Transducer Array and Liquid-Crystal Device, consists of a thick (DKDP) crystal, an off-axis scanning electron gun, and associated optics..This paper proposes the use of a matrix-type (nematic) liquid crystal display plate. as a component, permitting the reconstruction of acoustic or microwave targets..A preliminary experiment is also described.
