Abstract:
Provided is a hyperspectral sensor including a spectral angle converting unit configured to convert an angle of incident light differently according to a wavelength, a diffraction unit configured to selectively diffract the incident light according to an incident angle and a wavelength, a focusing optics including at least one lens, and configured to collect diffracted light passing through the diffraction unit, and an image sensor configured to acquire an image passing through the focusing optics and formed on a focal plane, wherein the diffraction unit includes a volume Bragg grating having a periodic refractive index distribution therein.
