Abstract: A noninvasive glucometer and a blood glucose detection method are provided. The noninvasive glucometer includes a light source, a spectrometer and detecting space into which an object to be detected intervenes; the detecting space is connected with the light source and the spectrometer respectively, so that a spectrum emitted by the light source can generate incident light entering the spectrometer after passing through the object to be detected. The spectrometer includes: an optical modulation layer configured to perform light modulation on the incident light to obtain a modulated spectrum; a photoelectric detection layer located below the optical modulation layer, and configured to receive the modulated spectrum and provide differential responses with respect to the modulated spectrum; and a signal processing circuit layer located below the photoelectric detection layer and configured to reconstruct the differential responses to obtain an original spectrum.

Abstract: An optical modulation micro-nano structure, a micro-integrated spectrometer and a spectrum modulation method are provided. The optical modulation micro-nano structure includes an optical modulation layer located on a photoelectric detection layer that can modulate incident light to form differential responses on the photoelectric detection layer, so as to obtain an original spectrum by reconstruction, thereby overcoming the defects that the existing spectrometers rely too much on precise optical components, which makes spectrometers bulky, heavy and expensive.
