Patent Images
1. A method of arranging and utilizing a multivariate optical computing and analysis system, the method comprising:
- transmitting a first light from a light source;
filtering the first light for a spectral range of interest of a sample;
directing the first light through a cavity in a direction of the sample;
directing a second light generated by a reflection of the first light from the sample through the cavity;
directing a portion of the second light with a beamsplitter;
arranging an optical filter mechanism in a normal incidence orientation to receive the portion of the second light, the optical filter mechanism being configured to optically filter data carried by the portion of the second light into at least one orthogonal component; and
measuring a property of the orthogonal component with a detector in communication with the optical filter mechanism to assess the data.
