Multilayer Optical Filters for Automatic Detection of Analytes in Mixtures with Interferrants - Basic Research in Materials and Techniques
Abstract
Research during the first year of the USC optical computing project demonstrated that multivariate optical elements (MOEs) could be designed, fabricated and characterized. Results of the first MOE tests revealed that near-theoretical performance could be obtained in the simple situations tested. New tools for designing MOEs were developed that bypass many anticipated problems. The limits of precision due to fabrication errors were assessed. Process control algorithms for fabrication that incorporate design tools periled fabrication of MOEs with performance exceeding those expected theoretically for real fabricated devices; this was achieved by redesigning MOEs on the fly to offset deposition errors. Design concepts were developed for imaging tools based on MOEs, and initial demonstrations were begun for imaging applications. Mid-infrared, near-infrared and Raman spectra were acquired for nearly 50 organophosphorus compounds to explore the regions of the spectral that are most definitive for their detection.
