Abstract:
1. A method of using multivariate optical computing to collect real-time data about a process stream of a target material, said method comprising: installing an optical analysis system proximate a process line, the process line having a transmissive window installed therein and being configured to move the target material past the transmissive window for analysis by the optical analysis system; using an optical element in the optical analysis system to form a first aperture and a second aperture, the optical element excluding light passing through the first aperture from passing through the second aperture; illuminating a portion of the target material in the area of the transmissive window with a modulated light from the optical analysis system through the first aperture; capturing a reflected light from the illuminated portion of the target material through the second aperture; directing a portion of said reflected light through at least one multivariate optical element in the optical analysis system to produce a stream of instantaneous measurement results; and continuously averaging the stream of instantaneous measurement results over a period of time to determine an overall measurement of said property of the target material.
