High-integration portable polarization regulation blood glucose measuring device and method

Abstract

The invention aims to solve the problems that due to the fact that a discrete polarization state controller is generally formed by cascading a plurality of discrete polarizing films, wave plates, electro-optical modulators and other polarized optical elements in an existing non-invasive blood glucose concentration detection device based on the Mueller matrix rotation method, the system size is large, control is complex, calibration needs to be carried out for many times and the cost is high, and the invention provides a high-integration portable polarization regulation blood glucose measuring device and method. The blood glucose measuring device comprises a light source module, a polarizer module, an analyzer module and a detector module; the light source module emits collimated parallel light and irradiates the polarizer module; the polarizer module regulates and controls the polarization state of incident light emitted by the light source module to generate a specific polarization state, the incident light enters a to-be-detected part of a human body, and after the light is reflected and passes through the polarization analyzer module, polarized light enters the detector module for polarization imaging and detection; the polarizer module and the polarization analyzer module use an integrated polarization state controller to conveniently regulate and control the polarization state of incident light.

Description

technical field [0001] The invention belongs to the field of human blood sugar detection, and in particular relates to a highly integrated and portable polarization-regulated blood sugar measuring device and method. Background technique [0002] At present, the routine detection methods of blood glucose can be divided into two categories, invasive blood glucose detection and non-invasive blood glucose detection. Traditional fully automated biochemical analyzers and finger blood glucose meters are invasive detection methods, mainly through blood samples taken by hospitals for analysis or finger pricks for detection through test strips. These methods all need to pierce the skin, and frequent collection. Not only does it cause psychological fear in the subjects, but it is also easy to cause infection. At the same time, the cost of testing is relatively high, and continuous blood sugar monitoring cannot be achieved. It brings great physical pain to the tested person; in additi...
