Abstract : This research involved the development of an ultraviolet (UV) hyperspectral imager. A hyperspectral image is a three dimensional image in which two of the dimensions provide spatial information and the third provides spectral information. In an effort to minimize the cost of this experiment, the NPS Middle Ultraviolet Spectrograph for Analysis of Nitrogen Gases (MUSTANG) instrument was modified to function as a hyperspectral imager. This required the design, fabrication, and testing of hardware and software to coordinate the operation of a two dimensional, charge coupled device (CCD) detector with a servo-controlled scanning mirror. Control and synchronization of scanning mirror and image collection was accomplished by software (written in Borland C++) run from an Intel microprocessor based PC. The benefits of a UV hyperspectral imager are primarily in the rea of Support to Military Operations (SMO). There are two principal applications: (1) target identification, and (2) battle damage assessment. Additionally, this instrument has dual use publications, namely, (1) redirection of jet aircraft to avoid the foreign object damage (FOD) hazards presented by volcanic ash clouds through analysis of the absorption of solar UV radiation by the sulfur ioxide (SO(2)) gas associated with volcanic ash, and (2) forest fire detection.
