Multilayer Optical Filters for Automatic Detection of Analytes in Mixtures with Interferrants - Basic Research in Materials and Techniques

摘要

Research during the second year of the USC optical computing project demonstrated that imaging multivariate optical elements (IMOEs) could be designed, fabricated and characterized. Results of the first MOE tests showed that the angle-independent performance anticipated in Y1 of this project is a practical possibility. Measurements were made on the UV-Vis, near-infrared and mid-infrared spectral characteristics of one bacterial spores type, specifically, the bacillus, BG, and comparisons to papers of many types were made. The results showed that these spores were distinguishable from typical papers in the UV-blue region, the 1500 nm region, and throughout the mid-IR. A prototype camera system based on an IMOE was constructed and demonstrated to work in the UV-Vis region.
