Paper Abstract

High definition color projection systems require substantial geometric precision in the co- projection of the red, green and blue images. A system for providing precise automatic geometry correction (automatic convergence) has been designed for the single lens light-valve projector. The correction system is independent of the main deflection, providing high precision with flexible scan capability. The hardware and software system, and methods for high resolution measurement, correction and control are described.
