Abstract
According to an embodiment, an optical device includes a light selection unit, an imaging element, and a deriving unit. The light selection unit splits an irradiated light beam into a plurality of spectral beams of different wavelength regions. The imaging element captures a subject irradiated with the spectral beams including beams of at least two different wavelengths to acquire a spectral image. The deriving unit derives a surface property or shape information of the subject from a specified result obtained by specifying, by the deriving unit, an irradiation region irradiated with each of the spectral beams on the subject based on a mixing ratio of the spectral beams and received light intensity of each of the spectral beams included in the spectral image.
