Abstract
Different objects require different imaging spectra, and a high-temporal-resolution imaging spectrometer has further
requirements for producing a large field of view(FOV). For these reasons, we present a new system based on a
staring/scanning area-array detector to allow for wide-FOV imaging, along with an acousto-optical tunable filter (AOTF)
to impart quick, programmable selection of spectra. Using AOTF as a dispersive component and a turntable as the
motion platform, we designed a staring, spectral-programmable imaging prototype with a working band of 400~1000
nm. Besides, we could obtain a large FOV by image mosaic. We performed imaging experiments and image processing
for an initial verification of this technique. This technical solution can be used not only for VNIR, but also in SWIR,
MWIR, and other bands; it adapts to spectral and FOV requirements for varying subjects, and provides an advanced
technical means for further application of high-resolution spectral imaging.
