Claim 7:
8. The beam deflector of claim 7, wherein the second sub deflector comprises:
a third deflection element configured to deflect light having the first polarization direction in the second direction;
a second general-purpose polarization conversion element configured to convert the polarization direction of the light of the first wavelength band and the polarization direction of the light of the second wavelength band; and
a fourth deflection element configured to deflect the light having the second polarization direction in the first direction, and
wherein the third deflection element, the second general-purpose polarization conversion element, and the fourth deflection element are sequentially provided such that the light of the first wavelength band and the light of the second wavelength band sequentially pass through the third deflection element, the second general-purpose polarization conversion element, and the fourth deflection element.
