Biomedical Applications of Near-Infrared Spectroscopy
While the various applications in this chapter are listed by topic — blood chemistry, blood oxygen, and so forth — there may be overlaps or applications where a single application is difficult to assign.
One of the most publicized and pursued uses of near-infrared (NIR) in the life sciences is for in situ glucose measurements. Anumber of patents for noninvasive blood-glucose devices have been issued. For instance, the one developed by Ham and Cohen , patent number 5,553,616, where the light is passed through the finger. The poster, by Gabriely et al.  acquired spectral data from the thumb and used it to measure clinically relevant plasma glucose scanning from 400 to 1700 nm with a fiber-optic probe.
