Abstract

One limitation of diffractive optical elements (DOEs) or zone plate lenses is abundant chromatic aberration. A previous report described a novel system that exploits this typically unwanted effect to create an Image Spectrometer [Lyons 1995]. A DOE performs the imaging and provides the dispersion necessary to separate a multispectral target into separate spectral images. A CCD is stepped or scanned along the optical axis recording a series of these spectral images. This paper reports on the DOE that was fabricated, simulated and implemented in a visible DOIS prototype. The data from this prototype can be interpolated to predict the performance of fieldable DOIS systems that can be designed to operate at ultraviolet, visible or infrared [Hinnrichs 1995] wavelengths for multispectral and hyperspectral imaging in medicine, forensics, industrial and environmental monitoring, as well as military applications.
