It must also have a spherical or plane wavefront since this facilitates duplicating the wavefront when an optical source is used to illuminate the hologram and form an image.

https://doi.org/10.1007/978-1-4612-3608-5olographic imaging is made by changing from linear detection to phase detection, respectively. The commercial availability of lasers and laser beam scanning devices permit the construction of acoustic imaging systems to be relatively straightforward, and with the appropriate devices and TV compatible circuitry, real time imaging is possible.

Attribution and Health-Related Functionings on the point source and the scanning is carried out either by mechanical motion of the object through this focal point or by “electronic scanning” wherein the phase of the incoming signal as collected by an array is carefully adjusted to synthesize a spherical lens.

Further Directions and Unresolved Questionss and clinicians have developed a great skill in the use of these instruments and a vast amount of information has been recorded by a careful, systematic exploration and correlation with known features. One prime example of the technique has been described by Dr. F. Weill. and his co-authors in Besancon, France.

Legal Data Protection Considerations,iled accounts of some of the more important (or popular) techniques receiving attention today. Therefore, in this chapter topics will be presented in a rather introductory fashion in order to assemble the concepts for ultrasonics imaging system analysis and synthesis.

By seeing the pulses of scattered light from the various objects he can readily obtain a mental image of the size, color and configuration of the various parts of the room and of the objects placed within it.
