Optics design for internal autoconverge in a single-lens light-valve projector

摘要

Abstract: Optics design for acquisition of image positional information suitable for geometry correction in a single projection lens, full-color light-valve projector. All signal acquisition and control is internal to the projector. Correction light path is separate, coaxial and color complementary to the projection light path. Design parameters for precision signal acquisition are discussed.!6
