INTEGRATED COMPUTATIONAL ELEMENT USING INCIDENCE ANGLE MANIPULATION

摘要

Multi-characteristic detection is achieved by altering the light incidence angle of a single Integrated Computational Element ("ICE") used in an optical computing device. The optical computing device manipulates the incidence angle of light interacting with the ICE, thereby enabling the detection of multiple sample characteristics. The effect of manipulating the light incidence angle is that the effective light path length through the ICE is altered, thus shifting the transmission spectral profile of the ICE.
