摘要： A system for inspecting the surface and internal threedimensional aspects of a solid object by directing a beam of spatially coherent sonic wave energy so that a portion of the wave energy which penetrates the object is reflected from interfaces between density discontinuities therein and is directed toward a recording plane as an object beam. Another portion of the beam of spatially coherent sonic wave energy is reflected directly from a reflecting surface and directed to the recording plane as a reference beam. The object beam and the reference beam form an interference fringe pattern at the recording plane which is recorded on a transparency. Thereafter, three dimensional images of the object can be reconstructed by directing a laser beam through the transparency and looking through the transparency.

摘要： In earth holography the reference wave is produced by generating a low amplitude cyclic vibration essentially at the earth''s surface and receiving this under steady-state conditions at the various geophones in the seismic spread. The resultant signal is recorded and its square wave fundamental component used in determining the reference wave employed in making the ultimate hologram.

摘要： A coherent monochromatic light beam is directed into a lightsound interaction cell in which a spatially modulated sound field of constant frequency-carrying image information is propagated nominally transversely to the beam by means of a transducer attached to the sound cell and driven by an appropriate constant frequency signal. The beam is focused about any desired point in the sound field so that a scattering interaction is obtained. The focal region is maintained narrower than the sound wavelength so that a temporal and spatial modulation is imparted to the light representative of the phase and amplitude of the sound field at the focal region. Interposed in the path of such modulated light is a photodetector preceded by a demodulator comprised of either a spatial filter or quarter-waveplate and analyzer. The photodetector extracts an output signal at the sound frequency whose phase and amplitude is representative of that of the sound field about the desired focal region. Such a signal may be recorded or displayed either conventionally, or holographically, if the output signal is mixed with a reference signal derived from the constant frequency transducer signal.

摘要： An acoustic interference pattern as manifested upon a compliant surface and caused by an impingent acoustic field carrying image information is visualized into an observable optical interference pattern which is photographed constitutes a hologram of the image information. A source beam of laser light is diffracted from the surface into a subject beam which is thereby modulated with the image information and frequency-shifted from the source light. The subject beam is separated from other diffracted light components and from background scattered noise light and directed to interfere with a reference beam at an angle such that spurious images are minimized. The reference beam is also derived from the source beam and also frequency-shifted for coherence with the subject beam, thereby forming stationary fringes representative of the acoustic interference pattern.

摘要： Both a radiation source and a radiation receiver are scanned relative to an object scene under investigation for obtaining holographic information as to the scene. By relating the relative movement of the source and receiver in a predetermined manner, various characteristics of the holographically reconstructed image of the object scene may be controlled. In one embodiment, the source and receiver are locked together and scanned relative to an object scene during the construction of a hologram capable of reconstructing an image of the object scene with twice the resolution that is obtained by ordinary holographic techniques. Apparatus for carrying out this improved scanning technique is disclosed in the embodiment of ultrasonic holography wherein a hologram is constructed directly on photographic film or displayed on a cathode ray oscilloscope.
