1. An optical analysis system for measuring compositions, comprising:

  • a light source being configured to radiate a first light;

    a modulator disposed in a ray path of the light, the modulator being configured to modulate the light to a desired frequency;

    a spectral element disposed proximate the modulator, the spectral element being configured to filter the light for a spectral range of interest of a sample;

    an optical filter mechanism disposed to receive a first light beam split from the light reflecting from the sample, the optical filter mechanism being configured to optically filter data carried by the first light beam into at least one orthogonal component of the first light beam;

    a first detector mechanism in communication with the optical filter mechanism to measure a property of the orthogonal component to measure the data carried by the first light beam;

    a second detector mechanism being configured to receive a second light beam split from the light reflecting from the sample for comparison of the property of the orthogonal component to the second light beam;

    an accelerometer being configured to sense when to acquire the data from the sample;

    a computer disposed in the system in communication with the first and second detector mechanisms for processing the data; and

    a battery system in electrical communication to provide stand-alone capability.
