Spherical beam volume holograms for spectroscopic applications: modeling and implementation
(Georgia Institute of Technology, 2004-12)
The spherical beam volume hologram, recorded by a plane wave and a spherical beam, is investigated for spectroscopic applications in detail. It is shown that both the diffracted and the transmitted beam can be used for ...
Compact Fourier-transform volume holographic spectrometer for diffuse source spectroscopy
(Georgia Institute of Technology, 2005-04)
We present a new idea for diffuse source spectroscopy using a Fourier-transform volume holographic spectrometer formed by a Fourier-transform lens, a volume hologram, and a CCD. We show that this spectrometer can operate ...
Role of recording geometry in the performance of spectral diversity filters with spherical beam volume holograms
(Georgia Institute of Technology, 2005-01)
We present experimental demonstrations of spectral diversity filters with spherical beam volume holograms for multimodal multiplex spectroscopy. Major properties of filters under diffuse-light illumination are discussed. ...
Analysis of slitless holographic spectrometers implemented by spherical beam volume holograms
(Georgia Institute of Technology, 2006-05)
The analysis of a slitless volume holographic spectrometer is presented in detail. The spectrometer is based on a spherical beam volume hologram followed by a Fourier-transforming lens and a CCD. It is shown that the ...
Multifunctional and compact spectrometers based on cylindrical beam volume holograms
(Georgia Institute of Technology, 2007-11)
We propose a new class of slitless spectrometers using cylindrical beam volume holograms. These holograms disperse an input beam in one direction in an output plane while they do not affect the beam in the perpendicular ...
