1. A non-invasive blood glucose detection device based on a multi-technology integration, comprising a main controller module, a display module, an acousto-optic tunable filter (AOTF) monochromatic light source module, a detection probe module and a data processing module; wherein:
the main controller module controls the AOTF monochromatic light source module to generate near-infrared orthogonal polarization monochromatic light which is transmitted to the detection probe module through an optical fiber; the detection probe module emits the near-infrared orthogonal polarization monochromatic light to a detection part; the detection probe module collects the near-infrared orthogonal polarization monochromatic light reflected by the detection part and converts an optical signal into an electric signal with polarization information and absorption intensity information; the detection probe module transmits the electric signal to the data processing module; the data processing module processes the electric signal and performs an A/D conversion on the electric signal, and then transmits the converted signal to the main controller module; the main controller module predicts a blood glucose value and displays the predicted blood glucose value on the display module.
