We are aiming to realize non-invasive blood glucose measurement in daily life.We obtained the possibility of glucose from mid-infrared light emitted from living body.Therefore, we developed a one-shot mid-infrared passive spectral imaging device that can apply the proposed method to wearable devices.Since this device consists of two lenses, it can be miniaturized to the size of a pea.In this report, we describe the principle of the device and the measurement results of DME gas using a blackbody as background light.
