Techniques for optical processing elements

摘要

One disclosed method for designing an integrated computational element (ICE) core includes generating with a computer a plurality of predetermined ICE core designs having a plurality of thin film layers, wherein generating the plurality of predetermined ICE core designs includes iteratively varying a thickness of each thin film layer by applying coarse thickness increments to each thin film layer, calculating a transmission spectrum for each predetermined ICE core design, calculating a performance of each predetermined ICE core design based on one or more performance criteria, identifying one or more predictive ICE core designs based on the performance of each predetermined ICE core design, and optimizing the one or more predictive ICE core designs by iteratively varying the thickness of each thin film layer with fine thickness increments, wherein the one or more predictive ICE core designs are configured to detect a particular characteristic of interest.
