Electronically Tuned Imaging Spectrometer with Variable Resolution

Abstract:

A high performance rapid scanning imaging spectrometer is proposed in response to
the requirements describe in NASA SWIR program solicitation subtopic No 08.19. The
proposed system uses an acousto-optic tunable filter (AOTF) as the wavelength tuning
device. A risk reduction effort is proposed for Phase I. The R&D tasks include (a)
to develop innovative approaches to vary the spectral bandpass of the AOTF; (b) to
perform theoretical and experimental research on the imaging characteristics of AOTFs.
The results of Phase I effort will be used for the design and construction of a high
performance imaging spectrometer in Phase II.
The AOTF to be developed in the proposed program can be used in a variety of commercial
applications that include industry process control (e.g., thin film monitoring, color
separation), multi-color display, pollution monitoring, optical communication (wavelength
multiplexing, covert communication) and medical instrumentation.
