Abstract
A display apparatus () has at least one color channel providing a modulated light for each of a plurality of image frames (). One or more laser sources that provide an illumination beam having a first polarization transmission axis. An imaging modulator () in the path of the illumination beam is actuable to direct the modulated light toward a projection lens. A laser blanking apparatus in the path of the modulated light is disposed to block transient light between image frames and has at least one analyzer () having a second polarization transmission axis that is orthogonal to the first polarization transmission axis and at least one light polarization modulator that is synchronously timed to rotate polarization of transient light during an interval between frames.
