Isini Treatment of Acid Mine Drainage

Not Available The Air Force desires compact, intelligent optical sensors for use on satellites and other unmanned space vehicles. Intelligent sensors combine detection, processing, and control functions onto a single package to allow for autonomous detection and interpretation of optical signals. A specific case where an intelligent optical system is needed is in the detection, processing, and evaluation of infrared polarization imagery, which has shown potential for improved target discrimination over other infrared imaging techniques. To meet this need we propose to develop an intelligent, compact, imaging infrared polarimeter on a chip. The key innovation on which this polarimeter will be based is the recent development of efficient lithographic antennas at mid and far-infrared wavelengths. These antennas can be integrated monolithically with a detector on the same substrate, and since the shape of an antenna determines its response to incident ramification, an antenna and detector combination can be made polarization selective. By fabricating the proper set of antenna shapes with their attached detectors onto a single substrate, a superpixel, which is capable of measuring the full Stokes vector can be developed. Reductions in size, cost, complexity, and improvement in speed over current systems are possible with a solid state polarimeter.
