Investigation of Holographic Testing Techniques ( Book )
2 editions published between 1970 and 1971 in English and held by 3 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)

Imaging Through Fibers, Phase 3 ( Book )
2 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

Imaging Through Fibers ( )
1 edition 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

Imaging through Fibers, Phase 2 ( )
1 edition published in 1997 in English and held by 1 WorldCat member library 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
Investigation of Image Formation in Scattering and Other Irregular Media ( )
1 edition 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
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
