02 Jan 1973TL;DR: An underwater acousto-optical imaging system for receiving water-borne acoustic waves representing an image of an object in the water and converting the image information to a corresponding optical image of the object is described in this paper.
Abstract: An underwater acousto-optical imaging system for receiving water-borne acoustic waves representing an image of an object in the water and converting the image information to a corresponding optical image of the object. The acoustic waves are focused by an acoustic lens into a Bragg coupling medium wherein a monochromatic light beam is Bragg diffracted by the acoustic waves to produce a modulated light side band defining the optical image. A television camera converts this optical image to electrical signals for viewing of the image at a remote video monitoring station. The imaging system may be driven in a scanning motion for operation in a search made and may include an acoustic source for generating acoustic probing waves which reflect from objects in the water back to and are converted to optical images by the imaging system.

TL;DR: In this paper, the phase shift suffered by an acoustic wave due to propagation through a region of local periodic surface heating was investigated, where the heating results from illumination of the sample surface by a focused intensity modulated light beam.
Abstract: We investigate the p eriodic phase shift suffered by an acoustic wave due to propagation through a region of local periodic surface heating. The heating results from illumination of the sample surface by a focused intensitymodulated light beam. Several methods are described for the measurement of the periodic acoustic phase shift. measurement can be used to probe the profile of the energy density in an acoustic beam. discussed are attempts to use the measurement to probe local applied stresses on the surface of a materi a1 . It is found that the Also

TL;DR: In this article, the high-frequency ultrasonic waves in a thin fiber for direct observation of the microscopic image of the tissue were transmitted through a reflector through the acoustic coupling medium using a tapered fused quartz fiber.
Abstract: We have studied to transmit the high-frequency ultrasonic waves in a thin fiber for direct observation of the microscopic image of the tissue. In the latest experiment, we observed the reflected wave from the end of the fiber at the frequency of approximately 160MHz, and the transmitted waves in the frequency from approximately 160MHz to 100MHz through the acoustic coupling medium. In this study, we report that the reflected waves (echoes) from a reflector through the acoustic coupling medium using a tapered fused quartz fiber could be detected.
