    Abstract: An optical 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 in communication with the spectral element, the cavity configured to direct the first light in a direction of the sample; a conical mirror configured to convert the first light reflecting from the sample into a second light, the cavity being further configured to direct the second light; 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; a first detector mechanism in communication with the optical filter mechanism to measure a property of the orthogonal component to measure the data; a second detector mechanism configured to receive the second beam for comparison of the property of the orthogonal component to the second beam; an accelerometer configured to control the data acquisition such that only detector signals during the period of time when the system is in the proper orientation such that the material sample (e.g., aspirin) is in proximity to the interrogation window are used for calculation; a computer having a data acquisition and conversion card, the computer disposed in the system in communication with the first and second detector mechanisms for signal processing; and a battery and charging system disposed in the system in electrical communication with the system to provide stand-alone operation capability.
