Design and First Operations of the Lineate Imaging Near-Ultraviolet Spectrometer (LINUS)

Abstract

Spectral imagery provides a new technology for target detection, defeat of camouflage, concealment and deception, and detection of chemical/biological agents in the atmosphere. The Lineate Imaging Near Ultraviolet Spectrometer (LINUS) is designed to image a narrow passband in the UV portion of the Electromagnetic spectrum. The imaging spectrometer views a 0.5 degree vertical strip, while observing a 20-40 nm wide band currently centered at 300 nm. The 512 x 512 pixel focal plane provides 0.1-1.0 nm spectral resolution, depending on slit width in the dispersive optic instrument. It is designed to scan a 2.5 degree horizontal pattern. The instrument has been calibrated spectrally, and its response to sulfur dioxide has been measured. First observations with the scanning instrument in the laboratory and outdoors at NPS are presented. This work demonstrates that LINUS can detect SO2 down to concentrations less than 100 ppm.
