Abstract

The diffractive optic imaging spectrometer, DOIS, is a compact, economical, rugged, programmable, multi-spectral imager. The design implements a conventional CCD camera and emerging diffractive optical element (DOE) technology in an elegant configuration, adding spectroscopy capabilities to current imaging systems (Lyons 1995). This paper reports on the visible prototype DOIS that was designed, fabricated and characterized. Algorithms are presented for simulation and post-detection processing with digital image processing techniques. This improves the spectral resolution by removing unwanted blurred components from the spectral images. DOIS is a practical image spectrometer that can be built to operate at ultraviolet, visible or infrared wavelengths for applications in surveillance, remote sensing, law enforcement, environmental monitoring, laser communications, and laser counter intelligence.
