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 in a direction of the sample;
directing a calibration light from a portion of the first light to a first detector and a second detector without interacting with 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 to the first detector and the second detector with a beamsplitter;
arranging an optical mechanism in a normal incidence orientation to receive the portion of the second light and the calibration light in the first detector, the opticalmechanism being configured to optically derive data carried by the portion of the second light and the calibration light into at least one orthogonal component; and
measuring a property of the orthogonal component with the first detector and measuring a portion of the second light and a portion of the calibration light with the second detector to assess the data.
