The present subject matter relates to 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. An exemplary 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 signal at a detector; and determining at least one property of the product based upon the detector output.

1. A method for high-speed analysis of samples, comprising: illuminating a sample with an illumination light at an inspection point by directing the illumination light through the sample;providing a light sensitive detector, the detector producing an output based on a received light;directing a light from the sample toward the light sensitive detector through at least one multivariate optical element, the light from the sample carrying information about the sample;directing at least a portion of the illumination light toward the light sensitive detector through a reference optical element; andanalyzing the signals produced by the detector, the analysis being based on a comparison of the signal produced from light passing through the at least one multivariate optical element and the signal produced from the portion of the illumination light passing through the reference optical element,wherein the same light sensitive detector is configured to receive the light from the sample and the portion of the illumination light passing through the reference optical element. 2. The method of claim 1, wherein the sample is at least one of a pharmaceutical tablet, a pharmaceutical powder, a food material, a chemical, a liquid, a gas, an emulsion, a solution, or a mixture thereof. 3. The method of claim 1, wherein the sample is a powder mixture in a closed container, the container being at least partially transparent to the illuminating light. 4. The method of claim 1, further comprising: moving the sample past the inspection point. 5. The method of claim 1, wherein directing a light from the sample comprises directing light reflected from the sample. 6. The method of claim 1, wherein directing a light from the sample comprises directing a light by way of a diversion path. 7. The method of claim 6, wherein directing a light comprises directing a light using a focusing lens. 8. The method of claim 7, wherein the focusing lens is a focusing mirror. 9. The method of claim 1, wherein directing light comprises directing light using a focusing lens. 10. The method of claim 9, where the focusing lens is a collimating mirror. 11. The method of claim 1, wherein the illumination light comprises a spectral-specific light. 12. The method of claim 11, further comprising: illuminating the sample through an optic window, the optic window being configured to focus the spectral-specific light onto a sample at the inspection point. 13. The method of claim 1 , wherein the sample comprises a plurality of discrete portions. 14. The method of claim 13, wherein the plurality of discrete portions are disposed in closed containers, the containers at least partially transparent to the spectral-specific light. 15. A method for high-speed analysis of samples, comprising: illuminating a sample with light at an inspection point by directing the light through the sample;providing a light sensitive detector, the detector producing an output based on received light;directing light from the sample toward the light sensitive detector through at least one multivariate optical element, the light from the sample carrying information about the sample;directing at least a portion of the sample illuminating light toward the light sensitive detector through a reference optical element; andanalyzing the signals produced by the detector, the analysis being based on a comparison of the signal produced from light passing through the at least one multivariate optical element and the signal produced from light passing through the reference optical element;wherein directing light toward the light sensitive detector comprises directing light through a plurality of multivariate optical elements, and wherein directing a portion of the sample illuminating light comprises directing a portion of the sample illuminating light through a plurality of reference optical elements. 16. The method of claim 15, wherein directing light comprises directing light alternately through differing multivariate optical elements and corresponding reference elements in sequence. 17. The method of claim 15 wherein the sample includes a mixture of oil and water. 18. The method of claim 1 wherein the reference optical element includes an adjustable aperture. 19. The method of claim 1 further comprising combining a portion of the light from the sample and a portion of the light directed through the reference optical element to measure a baseline. 20. The method of claim 1 wherein the sample includes a mixture of oil and water. 21. The method of claim 1 further including a second light sensitive detector configured to receive light from the sample and the portion of the illumination light passing through the reference optical element.
