摘要： A display apparatus (10) has at least one color channel providing a modulated light for each of a plurality of image frames (92). One or more laser sources that provide an illumination beam having a first polarization transmission axis. An imaging modulator (854, 85g, 85b) 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 (66) 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.

摘要： An illumination apparatus forms, onto a linear array light modulator, a line of illumination that extends in a linear direction. The illumination apparatus has a first laser array with laser emitters for forming a first linear beam array and a second laser array with laser emitters for forming a second linear beam array. An array combiner aligns at least the first and second linear beam arrays in the linear direction and directs the first and second linear beam arrays along a propagation path to form a mixed illumination. At least first and second cylindrical lens elements having power in the linear direction relay the mixed illumination from the propagation path toward the linear array light modulator. At least third and fourth cylindrical lens elements having power in the cross-array direction that is orthogonal to the linear direction focus the mixed illumination onto the linear array light modulator.
