Abstract:

The diffractive optic imaging spectrometer, DOIS, is a high resolution, compact, economical, rugged, programmable, multi-spectral images that can be built for ultraviolet, visible or infrared applications in surveillance, remote sensing, medical imaging, law enforcement, environmental monitoring, and laser counter intelligence. 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. In DOIS a DOE performs the imaging and provides the dispersion necessary to separate a multi-spectral target into separate spectral images. The CCD is scanned along the optical axis recording a series of spectral images in a process referred to as diffractive spectral sectioning. Under this project 3D spectralspatial DOE imaging theory was developed and implemented in software to predict the systems performance. A visible spectrum DOIS prototype was designed, fabricated, characterized and demonstrated with a variety of known targets.
