METHOD OF HIGH-SPEED MONITORING BASED ON THE USE OF MULTIVARIATE OPTICAL ELEMENTS
First Claim
1. A method of high-speed processing and monitoring, comprising:
- moving a product past an inspection point;
illuminating at least a portion of the product with a light;
directing light carrying information about the portion through at least one multivariate optical element to produce a first signal;
detecting the first signal at a first detector;
detecting a deflected portion of the light at a second detector; and
determining at high speed at least one selected property of the portion as the portion moves past the inspection point based upon the detector outputs.

Abstract
A method of high-speed processing and monitoring of a product, such as a pharmaceutical powder or tablet, comprises: moving the product (C) past an inspection station; illuminating at least a portion of the product with light; spectrally filtering a first portion of light carrying information about the product, o.g., transmitted or reflected light, by passing said first portion through at least one multivariate optical element (148) and detecting said filtered light with a first detector (152), —detecting a deflected second portion of said light with a second detector (156); and determining at least one selected property of the product based on the detector outputs.

9. A method of high-speed pharmaceutical processing and monitoring, comprising:
-
moving a plurality of portions of pharmaceutical product past an inspection point; illuminating at least one portion of the pharmaceutical product with a spectral-specific light though an optic window, the window configured to focus the spectral-specific light onto a portion at the inspection point; reflecting light carrying information about the portion through at least one multivariate optical element to produce a first signal; detecting the first signal at a first detector; detecting a deflected portion of the spectral-specific light at a second detector; and determining at high speed at least one selected property of the portion as the portion moves past the inspection point based upon the detector outputs. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of processing and monitoring a solid phase, the method comprising:
-
moving a solid product past an inspection point; illuminating the solid product with a spectral-specific light though an optic lens; reflecting light from the solid product through at least one multivariate optical element to produce a first signal, the reflected light carrying information about the solid product; detecting the first signal at a first detector; deflecting a portion of the reflected light in a direction of a second detector, the second detector configured to detect the deflected portion; and computing at high speed at least one selected property of the solid product as the solid product moves past the inspection point based upon the detector outputs. - View Dependent Claims (17, 18, 19, 20, 21)

22. A method of processing and monitoring a chemical, the method comprising:
-
moving a chemical past an inspection point; illuminating the chemical with a spectral-specific light though an optic lens; reflecting light from the chemical through at least one multivariate optical element to produce a first signal, the reflected light carrying information about the solid product; detecting the first signal at a first detector; deflecting a portion of the reflected light in a direction of a second detector, the second detector configured to detect the deflected portion; and computing at high speed at least one selected property of the chemical as the chemical moves past the inspection point based upon the detector outputs. - View Dependent Claims (23, 24, 25, 26, 27, 28)
