1. A device for non-invasive blood glucose concentration measurement, comprising:
a central control system;
a scattering module having an electronic control system of the scattering module connected to the scattering module, wherein the electronic control system of the scattering module is connected to the central control system, the scattering module comprises a detection element and a coherent radiation source connected to the coherent radiation source control system;
a transmission module having an electronic control system of the transmission module connected to transmission module, the transmission module being connected to the central control system, wherein the transmission module comprises a distal infrared radiation emitter and a proximal infrared radiation emitter and an infrared radiation detector; and
a proximity sensor that is connected to the central control system and an optical fiber probe comprising an emitting optical fiber and a measuring optical fiber, wherein the emitting optical fiber is connected to the coherent radiation source and the measuring optical fiber is connected to the detection element, wherein the emitting optical fiber and the measuring optical fiber are parallel to each other within the optical fiber probe and both the emitting optical fiber and the measuring optical fiber have a numerical aperture higher or equal to 0.5.
