20090002697 | Optical Analysis Systems and Methods for Dynamic, High-Speed Detection and Real-Time Multivariate Optical Computing - Multivariate optical analysis systems employ multivariate optical elements and utilize multivariate optical computing methods to determine information about a product carried by light reflected from or transmitted through the product. One method of processing and monitoring the product includes introducing the product at an inspection point; illuminating the product with a spectral-specific light though an optic lens; directing the light that has passed through at least a section of the product through at least one multivariate optical element to produce a first signal, the directed light carrying information about the product; detecting the first signal at a first detector; deflecting a portion of the directed light to produce a second signal in a direction of a second detector, the second detector configured to detect the second signal; and determining at least one property of the product at a rate of about one section of the product per second to about five sections of the product per second based upon the detector outputs. | 01-01-2009 |
20090219512 | OPTICAL ANALYSIS SYSTEM AND ELEMENTS TO ISOLATE SPECTRAL REGION - A method of selecting components for a multivariate optical computing and analysis system to isolate a spectral region includes selecting a spectral region of interest; selecting a spectral element with a predetermined transmission characteristic to control a spectral range of an illumination source; illuminating a sample with the illumination source; and analyzing an optical frequency returned by the sample relative to the spectral region of interest. | 09-03-2009 |
20090219538 | METHOD OF HIGH-SPEED MONITORING BASED ON THE USE OF MULTIVARIATE OPTICAL ELEMENTS - 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 ( | 09-03-2009 |
20090219539 | OPTICAL ANALYSIS SYSTEM FOR DYNAMIC REAL-TIME DETECTION AND MEASUREMENT - A method of real-time processing and monitoring comprises the steps of blending a material of interest (e.g., an active pharmaceutical material), with a secondary material, (e.g., an excipient), illuminating the blended materials with light, reflecting light carrying information about the blended materials through at least one multivariate optical element ( | 09-03-2009 |
20090219597 | OPTICAL ANALYSIS SYSTEM AND OPTICAL TRAIN - A multivariate optical computing and analysis system includes a light source configured to radiate a first light along a first ray path; a modulator disposed in the first ray path, the modulator configured to modulate the first light to a desired frequency; a spectral element disposed proximate the modulator, the spectral element configured to filter the first light for a spectral range of interest of a sample; a cavity disposed in communication with the spectral element, the cavity configured to direct the first light in a direction of the sample; a tube disposed proximate the cavity, the tube configured to receive and direct a second light generated by a reflection of the first light from the sample, the tube being further configured to separate the first and second lights; a beamsplitter configured to split the second light into a first beam and a second beam; an optical filter mechanism disposed to receive the first beam, the optical filter mechanism configured to optically filter data carried by the first beam into at least one orthogonal component of the first beam; and a detector mechanism in communication with the optical filter mechanism to measure a property of the orthogonal component to measure the data. | 09-03-2009 |
20100073666 | IN-LINE PROCESS MEASUREMENT SYSTEMS AND METHODS - A method of using multivariate optical computing in real-time to collect instantaneous data about a process stream includes installing an optical analysis system proximate a process line, the process line being configured to move a material past a window of the optical analysis system; illuminating a portion of the material with a light from the optical analysis system; directing the light carrying information about the portion through at least one multivariate optical element in the optical analysis system to produce an instantaneous measurement result about the portion; and continuously averaging the instantaneous measurement result over a period of time to determine an overall measurement signal of the material. | 03-25-2010 |
