More Information
Summary:Provided are a hyperspectral sensor and a hyperspectral camera in which influence of external information such as a reflecting material is reduced such that the spectral data accuracy of a subject to be acquired can be improved. In the hyperspectral sensor in which light from a subject is split into light components in a plurality of wavelength ranges by a spectral optical element and each of the light components in the wavelength ranges is received by a sensor array consisting of a plurality of photodetection elements to acquire spectral data in which spectral information of the subject is associated with each of the photodetection elements, a polarization diffraction element that emits polarized light is used as the spectral optical element.
