(57) [Summary]nA new non-invasive detection method for glucose or other constituents of interest in a sample has been developed. The apparatus and methods of the present invention provide an analog of human visual color perception, preferably in the near infrared region, replacing the spectrophotometer used in other non-intrusive near infrared detection methods. Multiple detectors are used, each covering a wide band of the detected spectrum, similar to color perception and colorimetry. In some situations, neural nets are used for analysis, allowing the system to learn. A novel method for background discrimination is also disclosed. |
