Method for non-invasive blood sugar measurement, involves arranging blood flowing area of human body between light source and detector, where human body area is analyzed by polarized rays of light

摘要

The method involves arranging a blood flowing area of a human body between a light source and a detector. The human body area is analyzed by polarized rays of light. The rays of light are transmitted with different plane of polarization and are modulated with a certain frequency. A change of the plane of polarization takes place with another frequency which is smaller than the former frequency. The changed plane of polarization is detected by the detector which has a polarization preferred direction. An independent claim is included for a device for non-invasive blood sugar measurement.
