ActiveUS20150355459A1Analogue computers for electric apparatusCharacter and pattern recognitionEnvironmental remediationGlobal optimization
A photometric system design methodology employs genetic algorithms to optimize the selection of optical elements for inclusion in the photometric system in order to improve system performance with respect to environmental conditions (i.e., to “ruggedize” the photometric system). The genetic algorithms utilize a multi-objective fitness function to evolve simulated optical element selection, which may be a combination of optical filters and integrated computational elements. The system may also output a size reduced database that serve as simulated candidate optical elements through global optimization, or may output a fixed number of simulated optical elements through conditional optimization for actual tool implementation and calibration analysis
