Abstract: Provided are a dual coupler device configured to receive lights of different polarization components, a spectrometer including the dual coupler device, and a non-invasive biometric sensor including the spectrometer. The dual coupler device may include, for example, a first coupler layer configured to receive a light of a first polarization component among incident lights. and a second coupler layer configured to receive a light of a second polarization component among the incident lights, wherein a polarization direction of the light of the first polarization component is perpendicular to a polarization direction of the light of the second polarization component. The first coupler layer and the second coupler layer may be spaced apart from each other and extended along a direction in which the light propagates in the first coupler layer and the second coupler layer.

Abstract: A spectroscopic apparatus and method for analyzing a biological material are provided. The spectroscopic apparatus may analyze a biological material which has an internal non-uniform tissue depending on a position thereof. The apparatus may include at least one detector configured to obtain respective detection spectrums corresponding to a plurality of measurement regions that are at mutually different positions of the biological material, and an information processor to determine whether the measurement regions are normal by mutually comparing the detection spectrums, or converting contribution degrees of data for a specific component of the biological material by differentiating the detection spectrums.
