Abstract:
A control device for a living body, using an optical measurement system for the living body, comprising:light incident means for simultaneously applying lights of at least one wavelength in a visible-infrared region to a plurality of incident positions on the surface of the living body, which includes light modulation means for intensity-modulating the applied lights with modulation frequencies which are different for each of said incident positions; light detection means for simultaneously detecting lights obtained by allowing said applied lights to pass through the living body at a plurality of detection positions on the surface of the living body, which includes selection and detection means for selecting and detecting transmitted light components corresponding to respective ones of said modulation frequencies at said respective detection positions from said applied lights relative to said plurality of detection positions; operation means for determining a type of output signal, based on the intensity of said transmitted light and a pre-stored reference data, and for outputting a signal indicative thereof as the type of output signal; memory means for storing the pre-stored reference data therein; and an external equipment for executing a functional operation according to the type of output signal from said operation means.
