Investigation of holographic testing techniques by Charles M Vest( Book )

4 editions published between 1969 and 1971 in English and held by 5 WorldCat member libraries worldwide

The report discusses holographic schemes for the detection of flaws in honeycomb panels and also describes the development of a method of reducing the sensitivity of holographic interferometry of transparent objects. An interferometric scheme for determining the surface roughness of flat objects is presented, and a planned application of the technique to curved objects is discussed. Recent advances in multiple-frequency holographic contouring are described, and a comparison of holographic and shadow-moire contouring schemes is presented. A computer simulation of acoustical holography and its use for reduction of aberration are also discussed. (Author)

Keywords include: optical processing; holography; white light; information processing; and phase conjugation
Imaging through fibers, phase 2 by Emmett N Leith( Book )

3 editions published in 1997 in English and held by 2 WorldCat member libraries worldwide

This Phase 2 effort demonstrated the transmission of an image using a single-mode fiber for the image and a second single-mode fiber for transmission of the reference beam. The prior Phase I effort transmitted the reference beam through free space. An acousto-optic cell provides a temporally incoherent source, from a spatially coherent reference input, that illuminates an object. The light is then transmitted through a lens to the back focal plane where the Fourier transform is observed. A single mode fiber, on-axis, at the back focal plane transmits the light to the receiving location. The reference input is transmitted through a second fiber to a second acousto-optic cell synchronized to the first. The two beams are mixed at the receiver, and the image is recovered by computer processing. Thus, the input spatial frequency components are translated to temporal frequencies and then back again. Three dimensional images were recovered with resolution near the theoretical limit
Imaging Through Fibers, Phase 3 by Emmett N Leith( Book )

3 editions published in 1998 in English and held by 2 WorldCat member libraries worldwide

Direct relay of images over single mode (SM) fiber has been demonstrated by coherence (holographic) methods. For the usual two dimensional case, the need is eliminated for prior digitization of input images, and no additional fiber coupling is required. Interestingly, the method functions for 3-D images just as well. Experiments carried out in the previous phase of this work demonstrated holographic image transmission over a pair of single mode fibers for the first time. The implementation utilized an available Acoustooptic (A/O) modulator reference signal relayed over the second SM fiber. This final phase of the project simulates the data rate capabilities of such a system if it were implemented with state of the art A/O cell and detector array technology. A computer stores the device parameters and provides the necessary coherent image processing. The study also details the performance improvements that would result from use of high performance Spatial Light Modulator (SLM) arrays in place of A/O cells for encoding of the reference phase. A 1-D SLM generates 2-D images as does the A/O, whereas a 2-D SLM array permits 3-D imaging. Data rates and signal/noise are analyzed for a wide range of parameters in both configurations. A rate of 4 GHz with a Bit Error Rate of 10 to the 6th power results from a particular SLM 1-D configuration based on existing device technology. A full system would require a second SLM for real time use. On the other hand the much simpler A/O based system would require developmental components to approach even a 1 GHz rate
White Light Optical Processing and Holography( Book )

2 editions published between 1981 and 1982 in English and held by 2 WorldCat member libraries worldwide

Methods for white light optical processing are reported. Convolution, including deblurring, in white light are described. Also described are methods for introducing a white light reference beam by means of an achromatic 3-grating interferometer, thus allowing a complex output to be recorded as a hologram. Experimental results are shown. (Author)
Investigation of Interferometric Waveguides( Book )

2 editions published between 1975 and 1977 in English and held by 2 WorldCat member libraries worldwide

The guiding of waves in interferometrically produced waveguides is investigated. A very general technique of analysis was developed. Computer calculations based on this approach were used to study leakage from guiding channels and the effect of pulse shape. Experimental results were obtained using poly methyl methacrylate as the recording material. Other first-order theories were developed. Thick grating couplers were formed in dichromated gelatin

Imaging through fibers by Emmett N Leith( Book )

2 editions published in 1996 in English and held by 1 WorldCat member library worldwide

An image is relayed in parallel over single mode optical fiber using the principles of physical optics (Holography). This is in contrast to all conventional fiber optic signal processing, which first converts all information into a sequential stream of bits or analog data. At this stage, a bundle is used only for intensification, and the required reference signal is sent separately in free space. Future work will incorporate even these last two system components into one single mode fiber. This is the first time this has been accomplished
Investigator of Coherence Imaging, Photon Migration, and Short-Pulse Image Processing( Book )

2 editions published in 2000 in English and held by 1 WorldCat member library worldwide

A theoretical investigation was made into the angular correlation that exists between two plane waves propagating through a scattering medium. Comparisons were made with the coherence existing between the angular correlation and the correlation of the exiting waves with a reference wave. Such studies are important to understanding how a wave field can be recovered after propagation through a scattering medium. A new concept, that of spatial filtering time gating, was investigated. This idea enables propagation through scattering media to be studied in a simple way unencumbered by the complexities of short coherence length interference. New concepts in confocal imaging were explored relating this process to volume holography and to synthetic aperture imaging. Confocal imaging theory was reformulated in the broadest possible way, giving rise to a basic theory of confocal imaging that encompasses all confocal imaging processes in their many diverse forms including the novel forms developed here. A new method of recording scattered light was developed. This method is based on up-conversion in non-linear crystals and records only the light component in which the propagation vector is aligned along some preferred axis. This method will further improve the capability for imaging of objects embedded in scattering media. Phase conjugation methods were employed in a novel way to detect objects embedded in scattering media
Investigation of Superresolution by Incoherent to Coherent Conversion( Book )

1 edition published in 1991 in English and held by 1 WorldCat member library worldwide

The superresolution method was applied to the problem of imaging through inhomogeneities. The process was combined with phase conjugation imaging, thereby producing a very generalized process for imaging through inhomogeneities. In particular, a one-pass phase conjugation process is effectively converted into a two-phase conjugation process. In addition, various other related methods for imaging through inhomogeneities were invented, the most successful being a process that combines electronic holography with femtosecond pulse technology
Investigation of Image Formation in Scattering and Other Irregular Media( Book )

2 editions published in 2005 in English and held by 1 WorldCat member library worldwide

A new theory of image formation through scattering media was developed based on Fourier optics and optical information concepts. This theory predicts the capabilities and limitations of the first-arriving-light method of imaging through highly scattering media in a way that is totally different from conventional transport and diffusion theory. A highly generalized theory of optical sectioning by holographic means was carried out. The method shows the basic similarities between broad-source optical sectioning and broad-spectrum optical sectioning. An especially intriguing observation is that broad-spectrum light gives a broad source effect, thus tying together the basic van Cittert spatial coherence theory and the Wiener-Khinchine temporal coherence theory. The authors developed a method of nonholographic incoherent optical sectioning that is easily implemented, gives good optical sectioning in reflection, and gives second-order sectioning in transmission. They also invented a new type of confocal imaging system, the chirp confocal, that combines technologies from four diverse disciplines: synthetic aperture imaging, chirp pulse compression, holography, and conventional confocal imaging. Extensive experimental work was done to verify the ideas that were developed
