Abstract
An apparatus and method for non-invasive determination of attributes of human tissue by quantitative infrared spectroscopy. The system includes subsystems optimized to contend with the complexities of the tissue spectrum, high signal-to-noise ratio and photometric accuracy requirements, tissue sampling errors, calibration maintenance problems, and calibration transfer problems. The subsystems include an illumination subsystem, a tissue sampling subsystem, a spectrometer subsystem, a data acquisition subsystem, and a processing subsystem. The invention is applicable, as examples, to determining the concentration or change of concentration of alcohol in human tissue.
