Claim 0:
1. A hyperspectral image sensor comprising:
an optical irradiator configured to irradiate light to a partial region of an object;
an optical path adjustment element configured to adjust a path of detection light generated in a plurality of different sub-regions included in the partial region in response to the irradiated light;
an optical detector configured to receive the detection light from the optical path adjustment element and generate a plurality of spectrum signals, each of the plurality of spectrum signals corresponding to a respective sub-region of the plurality of different sub-regions included in the partial region; and
a processor configured to generate a hyperspectral image of the partial region based on the plurality of spectrum signals,
wherein the optical irradiator comprises a first light source array including a plurality of first light sources arranged in a first direction, a second light source array including a plurality of second light sources arranged in the first direction and being separated from the first light source array and a transmissive window extending in the first direction and disposed between the first light source array and the second light source array, the first light source array being arranged in parallel to the second light source array,
wherein the optical path adjustment element is arranged to receive the detection light from the plurality of different sub-regions in a third direction through the transmissive window and adjust the path of the detection light so that the detection light is transmitted toward the optical detector in a second direction perpendicular to the first direction, the third direction being perpendicular to each of the first direction and the second direction,
wherein the optical detector comprises:
a lens configured to receive the detection light generated in the plurality of different sub-regions included in the partial region,
a spectrum filter configured to output a plurality of sub-spectrum filter signals for each sub-region of the plurality of different sub-regions based on the detection light, the plurality of sub-spectrum filter signals corresponding to a plurality of different wavelength bands for each sub-region of the plurality of different sub-regions, and
a spectrum signal generator configured to generate a plurality of sub-spectrum signals for each sub-region of the plurality of different sub-regions based on the plurality of sub-spectrum filter signals.
