An image collection chip, an object imaging recognition device and an object imaging recognition method are provided. The image collection chip comprises an optical modulation layer and an image sensing layer. The optical modulation layer is located on the image sensing layer. The optical modulation layer is provided with at least two modulation units and the image sensing layer is provided with sensing units corresponding to the at least two modulation units in a form of up and down. Each of the at least two modulation units is provided with at least one modulation subunit. Two or more modulation units among the at least two modulation units have different graphic structures, and the two or more modulation units having different graphic structures have different modulation roles on spectrum.

Image collection chip, object imaging recognition device and object imaging recognition method

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.

Noninvasive glucometer and blood glucose detection method

An image collection chip, an object imaging recognition device and an object imaging recognition method are provided. In each set of the pixel confirmation modules of the chip, each modulation unit and each sensing unit are correspondingly provided up and down on the optical modulation layer and the image sensing layer respectively; each modulation unit is provided with at least one modulation subunit, and each of the modulation subunits is provided with several modulation holes penetrating into the optical modulation layer; and the respective modulation holes in a same modulation subunit are arranged into a two-dimensional graphic structure having a specific pattern.
