Abstract
Provided is a beam deflector including a first sub deflector configured to deflect light of a first wavelength band in a first direction and a second direction that intersects the first direction, and convert a polarization direction of the light of the first wavelength band, and a second sub deflector configured to deflect light of a second wavelength band, that is different from the first wavelength band in the first direction and the second direction, and convert a polarization direction of the light of the second wavelength band, wherein the first sub deflector and the second sub deflector are sequentially provided such that the light of the first wavelength band and the light of the second wavelength band sequentially pass through the first sub deflector and the second sub deflector.
