Non-invasive glucose monitoring device

The present invention provides a non-invasive glucose monitoring device, comprising: a light source emits light; a first beam splitter, a focusing function; photo detectors, measuring reflected by the eyeball, and then transferred by means of a first beam splitter to optical information light and the absorption energy information photodetector group; reference element, receives the light from the first beam splitter, light reflected by the reference element by transmitted by the first beam splitter to the photo detectors, which is emitted from the light source by means of light transmitted by the first beam splitter to the photodetector group and the eyeball to form a first optical path, and the light emitted from the light source transmitted by the first beam splitter to the photodetector and the reference element group is formed a second optical path; The processing unit receives and processes information and the optically absorbing energy information to obtain glucose information.
