Diffraction Imaging in Depth

69th EAGE Conference and Exhibition incorporating SPE EUROPEC 2007, 2007
ABSTRACTHigh resolution imaging is of great value to an interpreter, for instance to enable identification of small scale faults, and to locate formation pinch‐out positions. Standard approaches to obtain high‐resolution information, such as coherency analysis and structure‐oriented filters, derive attributes from stacked, migrated images.

Reconstruction in diffraction imaging

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1989
The problem of reconstruction in imaging systems that are modeled using the Helmholtz wave equation (diffraction imaging) is addressed. A spectral analysis of the available diffraction data is presented to help develop algorithms and constraints on a diffraction imaging system's parameters for accurate reconstruction of the desired image.

Diffraction Line Imaging

2020
We present a novel computational imaging principle that combines diffractive optics with line (1D) sensing. When light passes through a diffraction grating, it disperses as a function of wavelength. We exploit this principle to recover 2D and even 3D positions from only line images.

Diffraction Images in the Polarizing Microscope

Journal of the Optical Society of America, 1959
In the polarizing microscope set for extinction, only that image whose polarization has been altered is available to form an image. The lenses themselves introduce such an alternation by rotation of the plane of polarization of rays having oblique incidence.

Diffraction Imaging Based on the Diffraction Operator

Proceedings, 2011
Seismic diffractions carry detailed structure information. Some of these structures are well-known as common hydrocarbon traps, such as faults, pinch-outs, unconformities and structures the size of which is in the order of the wavelength. Therefore, the development of computational resource capable of detecting diffractor points with a good resolution ...

Fresnel Coherent Diffractive Imaging

Physical Review Letters, 2006
We present an x-ray coherent diffractive imaging experiment utilizing a nonplanar incident wave and demonstrate success by reconstructing a nonperiodic gold sample at 24 nm resolution. Favorable effects of the curved beam illumination are identified.

Diffraction imaging for fracture detection

69th EAGE Conference and Exhibition - Workshop Package, 2007
The present way in fractures studies usually consists in using indirect indicators such as anisotropy, well log information etc. On the other hand, it is diffracted waves that contain direct and the most valuable information about fracture presents in the subsurface.
