Abstract
The Compact Wide Swath Imaging Spectrometer (CWIS) is a pushbroom imaging spectrometer for the solar reflected spectrum (380-2510 nm) with wide swath (1600/1280 elements), fast optical speed (F/1.8), and high uniformity (≥95%). CWIS is currently being tested at the Jet Propulsion Laboratory and is intended to address the need for high signal-to-noise ratio (SNR) compact imaging spectrometer systems for the visible to short wave infrared wavelength (VSWIR) range. We give an overview of the instrument functionality, describe the spectrometer alignment and system integration and report laboratory data that include spatial, spectral and radiometric calibration.
