LIGHT VALVE PROJECTOR HAVING AN IMPROVED BAR PLATE CONFIGURATION

摘要

A light valve projector of the Schlieren dark field type is provided with an improved input bar plate configuration which achieves greater light efficiencies. The improved input bar plate has orthogonally related rows and columns of slots in which the row slots are spaced between the column slots. Alternating rows of lenslets of a first array divide columns of lenslets of a second array. Light filtering is provided such that one color passes through the row slots and another color passes through the column slots. The output bar plate has a configuration which is complementary to the input bar plate.
