SYSTEM FOR NONINVASIVE DETERMINATION OF ALCOHOL IN TISSUE

摘要

An apparatus and method for non-invasive determination of attributes of human tissue by quantitative infrared spectroscopy to clinically relevant levels of precision and accuracy. 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/modulation subsystem, a tissue sampling subsystem, a calibration maintenance subsystem, an FTIR spectrometer subsystem, a data acquisition subsystem, and a computing subsystem.

1. An apparatus for determining an analyte property of a sample, comprising:
a. An illumination subsystem comprising a semiconductor light source; b. A sampling subsystem, mounted with the illumination subsystem such that light from the illumination subsystem is directed to a sample by the sampling subsystem; c. A data acquisition subsystem, mounted with the sampling subsystem such that light from the sample is communicated from the sampling subsystem to the data acquisition subsystem; d. A computing subsystem, mounted with the data acquisition subsystem such that the computing subsystem can determine the analyte property from information from the data acquisition subsystem.
