Abstract: An infrared three-dimensional imaging system and method in which an object is irradiated by monochromatic radiation in the near-infrared or mid-infrared region of the spectrum. A spectral image is captured for each wavelength in a spectral range by a radiation detector to create a spectral image data block that is stored on a data storage device. The object is rotated by some predetermined angular increment until a complete three hundred and sixty degree view is obtained so that a spectral image data block is created for each angular position. Each spectral image data block is compressed to its most relevant spectral information and used to re-create a three dimensional image by a known computerized tomography algorithm.

Abstract: The present invention includes an ATR crystal system comprising: an ATR crystal, one face of the ATR crystal forming a portion of an interior surface of a containment vessel, a radiation source for creating a beam or radiation, the radiation sources optically connected to an input area of the ATR crystal; and a detector for recording the beam of radiation, the detector optically connected to an output area of the ATR crystal. The present invention also includes a method of sample analysis utilizing an ATR crystal embedded in a containment vessel comprising the steps of: providing a containment vessel having an ATR crystal embedded therein; generating a monochromatic beam of light; transmitting the beam to an input of the ATR crystal; transmitting the beam from an output of the ATR crystal to a detector; and recording a signal from the detector.
