Classification: CPC G | IPC G

Claim 3:
4. The beam deflector of claim 1, wherein the first sub deflector comprises:
a first deflection element configured to deflect light having a first polarization direction in the second direction;
a first 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 second deflection element configured to deflect light having a second polarization direction that is different from the first polarization direction in the first direction, and
wherein the first deflection element, the first general-purpose polarization conversion element, and the second 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 first deflection element, the first general-purpose polarization conversion element, and the second deflection element.
