Low Absorption Liquid Crystal Materials for Midwave Infrared
… matters with applications spanning from visible, infrared, millimeter wave, to terahertz. In addition to direct-view displays and projection displays, liquid crystal is also widely used in adaptive optics, tunable-focus lens, and laser beam steering. Although the visible region has well developed …

Early Forest Fire Detection Using Texture, Blob Threshold, and Motion Analysis of Principal Components
… filtering followed by entropy filtering of the infrared (IR) video data, and (2) Principal Component Analysis of visible spectrum video data followed by motion analysis and adaptive intensity threshold. The two schemes presented are tailored to detect the fire core, and the smoke plume, …

Median filtering for target detection in an airborne threat warning system
… of point targets and blurred point targets in midwave infrared imagery is difficult because few assumptions can be made concerning the characteristics of the background. In this thesis, real time spatial prefiltering algorithms that facilitate the detection of such targets in an airborne threat …

Optically Pumped Type-II Mid-Infrared Tunable Distributed Feedback Lasers
Optically-pumped type-II mid-infrared index-coupled tunable distributed feed- back (DFB) semiconductor lasers have been developed to provide continuous-wave (CW) single longitudinal mode (SLM) operation with features including narrow spec- tral linewidth, high output power, good beam quality and …

Unipolar barrier strained layer superlattice infrared photodiodes : physics and barrier engineering
… (T2SL) is an emerging technology for infrared detection. They are being seen as a threat to 50 years old incumbent technology based on Mercury-Cadmium-Telluride (MCT) system. T2SL have been theoretically predicted to outperform MCTs. This dissertation has been aimed at improving the …
