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 ...
Dynamic optical correlation using localized holography
(Georgia Institute of Technology, 2007-03)
A new technique for optical correlation using gated holographic recording is demonstrated. Several persistent holograms are localized within separate slices as close as 33 μm apart along the crystal. Individual holograms ...
Optical correlation using gated localized holography
(Georgia Institute of Technology, 2005-08)
We present a new technique for optical correlation using gated holographic recording by which the holograms are localized in separate slices along the recording medium. We compare the performance of localized holographic ...
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. ...
Qualitative demonstration of spectral diversity filtering using spherical beam volume holograms
(Georgia Institute of Technology, 2004-06)
We investigate the feasibility of designing spectral diversity filters using spherical beam volume holograms. Our experimental results qualitatively show the separation of the information of different incident wavelength ...
