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;
dividing light carrying information about the portion of the product with a beam splitter into a first light portion and a second light portion, the first light portion and the second light portion having spectral characteristics;
after dividing the light with the beam splitter, directing the first light portion through at least one multivariate optical element to produce a first signal;
detecting the first signal at a first detector;
directing the second light portion in a direction of a second detector, the second detector configured used to detect the second light portion; 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 through an optic window, the window configured to focus the spectral-specific light onto a portion at the inspection point; dividing light carrying information about the portion of the pharmaceutical product with a beam splitter into a first light portion and a second light portion, the first light portion and the second light portion having substantially similar spectral characteristics; after dividing the light with the beam splitter, 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; directing the second light portion in a direction of a second detector, the second detector configured to detect the second light portion; and determining at high speed at least one selected property of the portion as the portion moves past the inspection point based upon the first and second detector outputs. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of processing and monitoring a solid product, the method comprising:
-
moving a solid product past an inspection point; illuminating the solid product with a spectral-specific light through an optic lens; dividing light carrying information about the portion of the solid product with a beam splitter into a first light portion and a second light portion, the first light portion and the second light portion having substantially similar spectral characteristics; after dividing the light with the beam splitter, directing light from the solid product through at least one multivariate optical element to produce a first signal, detecting the first signal at a first detector; directing the second light portion in a direction of a second detector, the second detector configured to detect the second light 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 through an optic lens; dividing light carrying information about the chemical with a beam splitter into a first light portion and a second light portion, the first light portion and the second light portion having substantially similar spectral characteristics; after dividing the light with the beam splitter, directing the first light portion through at least one multivariate optical element to produce a first signal, detecting the first signal at a first detector; directing the second light portion in a direction of a second detector, the 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)
