Laser or narrow band light sources are utilezed to from left (R1, G1, B1) and right (R2,G2;B2,) images of a 3D projection. Under off -axis viewing of projections (i.e. oblique incident angles) the passbands of the viewing filters in the glasses are blue- shifted, which has the potential of cause ctosstalk and/or loss of energry/brightness in any channel or color. This blue- shift is compensated via the combined use of any of viewing passbands (220) encompssing the associated projected lightband (222) and a red-shift passband (224) selection ofpassband wavelengths that maximize usability of the passband as it "shifts" due to varying or increasing angles of off -axis viewing), curvarure of viewing filters, and guard bands between light bands of adjacent channels. Implemented with any number of light sources, additional light sources are utilized to affecta desirable increase in color gamut. |
