Acousto-optic Imaging in Different Fields of Acoustics
نویسندگان
چکیده
A very short introduction of the principles of light diffraction by ultrasonic waves is followed by a discussion of acousto-optic imaging (schlieren) techniques. This method is often useful to obtain qualitative results of various acoustic phenomena in ultrasonics, underwater sound, material characterization, transducer performance and other areas of acoustics. Examples from different fields of acoustics and some scale model studies will be given, illustrating under what conditions this method can be used to obtain information about sound fields, without having to introduce a probe, hydrophone or other devices.

Detection of the tagged or untagged photons in acousto-optic imaging of thick highly scattering media by photorefractive adaptive holography We propose an original adaptive wavefront holographic setup based on the photorefractive effect (PR), to make real-time measurements of acousto-optic signals in thick scattering media, with a high flux collection at high rates for breast tumor detection.

متن کاملApplications of In – Fiber Acousto – Optic Devices
Nowadays, in-fiber acousto-optic devices are increasingly used as frequency shifters, multiplexers, modulators, and tunable filters. They can be easily spliced into optical fiber systems, and the consequent low insertion loss, make them an attractive alternative to bulk optics devices. Our group, established at the Institute of Materials Science, Department of Applied Physics, of the Valencia U...
متن کاملInfluence of Strong Acoustic Anisotropy on Reflection of Bulk Acoustic Waves in Crystals
Propagation and reflection of plane elastic waves in the acousto-optic crystals tellurium dioxide and calomel as well as in the ferroelectric material barium titanate is examined in the paper. The reflection of the waves from a free and flat boundary separating the crystal and the vacuum is investigated in the (001) planes of TeO2, Hg2Cl2, and BaTiO3 in the case of glancing acoustic incidence o...

The ability to generate efficient giga-terahertz coherent acoustic phonons with femtosecond laser makes acousto-optics a promising candidate for ultrafast light processing, which faces electronic device limits intrinsic to complementary metal oxide semiconductor technology. Modern acousto-optic devices, including optical mode conversion process between ordinary and extraordinary light waves (an...
متن کاملDesign and Implementation of a High-Speed Solid-State Acousto-Optic Interference Pattern Projector for Three-Dimensional Imaging
A novel method of projecting interference patterns using acousto-optics has been developed and implemented in the context of the Accordion Fringe Interferometry (AFI) three-dimensional measurement technique developed at MIT Lincoln Laboratory. AFI is an active technique that relies on projecting interference fringes and triangulation to recover range information. AFI is suitable for a wide rang...
