Abstract
The light source produces two colors and is combined with an optical dispersive element for the wavelength-dependent rotation of the plane of polarization of a light beam transmitted by the dispersive element, the layer having a modulation characteristic to enable each modulation element in combination with the polarizer to transmit or to block one color or the other color of the two colors produced by the light source.
