ABSTRACT:
An optical system is disclosed, including: an optical deflecting array including a plurality of optical deflecting devices arranged in a two-dimensional array, each of optical deflecting devices displacing a member having an optical reflection area and deflecting light, so that an incoming light flux entering the optical reflection area is deflected to a reflection direction being changed, a light source illuminating the optical deflecting array, and a projection lens projecting reflected light from the optical deflecting array based on color information. Each of the optical deflecting devices deflects light to two-axis directions, incoming light fluxes having different colors enter each of the optical deflecting devices from two directions respectively corresponding to two deflection axes, and are reflected by each of the optical deflecting devices based on the color information; and each of reflected light fluxes is led to the projection lens for a respective arbitrary time.
