CIRCULAR DICHROISM MEASURING DEVICE FOR LIVING BODY, CIRCULAR DICHROISM MEASURING METHOD FOR LIVING BODY, NONINVASIVE BLOOD SUGAR LEVEL MEASURING DEVICE AND NONINVASIVE BLOOD SUGAR LEVEL MEASURING METHOD

摘要

The objective of the present invention is to provide a novel measuring device and measuring method for estimating, easily, noninvasively and with high precision, blood sugar level of a person where conventionally blood had to be drawn to measure the blood sugar level, for treatment or prevention of diabetes. To achieve this objective, a method was adopted in which a wavelength of a variable wavelength laser light or a length of an excitation polarization maintaining optical fiber (PMF) is changed in synchronization with the pulse, a left and right circularly polarized light state of an output light thereof is made to change periodically, and the light is entered into the living body via the PMF.
