Dispersion multiplexing with broadband filtering for miniature spectrometers
(Georgia Institute of Technology, 2007-01)
We replace the traditional grating used in a dispersive spectrometer with a multiplex holographic grating to increase the spectral range sensed by the instrument. The multiplexed grating allows us to measure three different, ...
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 ...
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 ...
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 ...
