Abstract
Systems, devices and methods for noninvasive analysis of tissue, by irradiating a surface of the tissue with infrared radiation such that an interaction of the radiation with a component of the tissue other than water in two spectral bands is substantially identical, measuring an intensity of the radiation that emerges from the tissue in each of the spectral bands, determining change in at least one of shape and intensity of signals received by the at least one radiation detector, calculating a relative absorption by the tissue of radiation in one of the first and second spectral bands relative to absorption by the tissue of radiation in the other of the first and second spectral bands, and determining concentration of a predetermined substance, in accordance with the calculated relative absorption and in accordance with determined change in the received signal.
