Technical Abstract
“A Tunable Fabry-Perot Filter for Imaging Spectroscopy in the Infrared”,
SPIE Vol. 4574, pp. 153-61, (2002), C. Schwarze, J. Rentz, D. Carlson, R.
Vaillancourt, G. Genetti, and J. Engel.
We present a new hyperspectral imaging system for the long wave infrared
(LWIR) based on a tunable first-order Fabry-Perot Scanning Spectrometer
(FPSS). The FPSS operates over 8 – 12 mm with a spectral resolution of 1%
of the wavelength. The FPSS has a 22 degree field of view and a spatial
resolution of 0.11 degrees. The key components of the FPSS system are the
collection optics, a tunable Fabry-Perot etalon, optical position sensors, a
closed-loop positioning system, an uncooled microbolometer focal plane
array, a digital frame grabber card, and a user-friendly Graphical User
Interface (GUI).
