Tandem Fabry-Perot Etalon Cylindrical Beam Volume Hologram For High Resolution/Large Spectral Range Diffuse Light Spectroscopy
US Patent:
8203716, Jun 19, 2012
Filed:
Aug 3, 2007
Appl. No.:
12/447992
Inventors:
Omid Momtahan - Foothill Ranch CA, US
Chao Ray Hsieh - Atlanta GA, US
Ali Adibi - Suwanee GA, US
Chao Ray Hsieh - Atlanta GA, US
Ali Adibi - Suwanee GA, US
Assignee:
Georgia Tech Research Corporation - Atlanta GA
International Classification:
G01J 3/45
US Classification:
356454
Abstract:
Systems and methods for performing two-dimensional (2D) high resolution spectral-spatial mapping are described. At least one embodiment includes a spectrometer for performing two-dimensional (2D) high resolution spectral-spatial mapping comprising a Fabry-Perot component configured to receive a diffuse input beam and provide a high resolution spectral mapping of the diffuse input beam in a first direction. The spectrometer further comprises a volume hologram for increasing a spectral operating range, the volume hologram configured to perform spectral mapping in a second direction orthogonal to the first direction to increase the spectral operating range. The spectrometer further comprises a charged coupled device (CCD) configured to receive output beams, the output beams used to provide spectral analysis of the input beams.
Systems And Methods For Utilizing Cylindrical Beam Volume Holograms
US Patent:
8213008, Jul 3, 2012
Filed:
Jul 31, 2007
Appl. No.:
12/671166
Inventors:
Omid Momtahan - Foothill Ranch CA, US
Chao Ray Hsieh - Atlanta GA, US
Ali Adibi - Suwanee GA, US
Chao Ray Hsieh - Atlanta GA, US
Ali Adibi - Suwanee GA, US
Assignee:
Georgia Tech Research Corporation - Atlanta GA
International Classification:
G01B 9/02
US Classification:
356326, 356451, 356454
Abstract:
Systems and methods for performing spectral-spatial mapping in (one and two dimensions) and coded spectroscopy are described. At least one embodiment includes a system for performing spectral-spatial mapping and coded spectroscopy comprising a cylindrical beam volume hologram (CBVH), the CBVH configured to receive input beams and generate diffracted beams in a first direction to perform spectral-spatial mapping, the CBVH further configured to allow input beams to pass in a second direction orthogonal to the first direction unaffected. The system further comprises a first lens configured to receive the diffracted beams and perform a Fourier transform on the input beams in the first direction, a second lens configured to receive the diffracted beams and focus the beams in the second direction to generate output beams, and a charged coupled device (CCD) configured to receive the outputs beams, the output beams used to provide spectral analysis of the input beams.
Non-Volatile Holographic Storage In Doubly-Doped Photorefractive Material
US Patent:
6157470, Dec 5, 2000
Filed:
Feb 25, 1999
Appl. No.:
9/260523
Inventors:
Karsten Buse - Ghhuette, DE

International Classification:
G03H 102
G03H 104
G11C 1122
G03H 104
G11C 1122
US Classification:
359 7
Abstract:
A non-volatile holographic recording method and system based on a doubly-doped photorefractive material. One embodiment of the holographic material is doped to have first and second types of dopants that are operable to produce charge carriers to a common band in response to radiation of a specified wavelengths. Charge carriers in the common band can migrate to a different spatial location. The dopants are also capable of recombining with charge carriers in the common band. The first type of dopants have a first dopant energy level below the band by a first energy gap greater than a second energy gap of a second dopant energy level of the second type of dopants below the common band. The first and second dopant energy levels are separated from each other so that their absorption bands to the common band are substantially separated. In addition, the first and second energy gaps should be much greater than the thermal energy k. sub.
