Abstract
A beam deflector includes a first wavelength selective polarizer configured to convert a polarization state of light in a first wavelength band into a first polarization state, a first liquid crystal deflector including liquid crystal molecules and an optical path change surface to deflect light incident from the first wavelength selective polarizer, and a controller configured to control the first liquid crystal deflector to adjust an angle of the first optical path change surface.
