Instrument for measuring biological information and method for measuring biological information

摘要

Because of using a plurality of light sources and photodetectors, fluctuation of output characteristic among individual light sources and fluctuation of output characteristic among individual photodetectors impede a measurement in a satisfactory precision. The organism information measuring apparatus comprises an LED (105); a detecting region changer (108) for changing a position of a region of light emitted from the LED (105) that has passed through the organism and has again been emitted toward outside through the organism surface; a photodiode (104) for detecting the light that has passed through the detecting region changer (108); a computing unit (104) for acquiring light information related to the light detected by the photodiode (104), and generating information related to the organism referring to the light information and sample information; and a data storing unit (101) for storing the sample information.
