Abstract

A great deal of effort is presently being focused on developing high resolution, high sensitivity medium wavelength IR (MWIR) imaging systems for a variety of applications. These range from thermal imaging for industrial applications to military applications for detecting vehicles, missiles, etc. The present state-of-the-art method for MWIR imaging consists of fabricating linear and two-dimensional arrays of semiconductor detectors, such as HgCdTe, InSb, etc., and incorporating these into an appropriate optical imaging system. However, such devices are difficult to make and are very expensive. A new detector medium is described which can be fabricated at low cost for use in MWIR imaging. Specifically, the new medium is an electron trapping material capable of up-converting MWIR to visible wavelengths, which can be easily detected with a commercial camera system. This paper will describe the specific performance characteristics of the new phosphor material and its application in MWIR imaging.
