<p>A spatial light modulator (110R, 110G, 110B) includes a prism group (210) and satisfies either of the following conditions <DF>d<0.95x lambda /(2x(n-1)), </DF> <DF>d>1.05x lambda /(2x(n-1)) </DF> where d is a distance between a reference surface (901) and a flat surface (902b), lambda is a wavelength of an incident light, and n is a refractive index of the prism group. <IMAGE></p> |
