Optical projection system with a telecentric ray path for on-board aviation displays

In this paper, we discuss the design principles of an optical projection system that is compatible with a liquid-crystal display. We describe a procedure for synthesis of a complex optical system using conceptual design and third-order aberration theory. The resulting optical system design has high image quality over the entire field, low distortion, and high telecentricity, enabling liquid-crystal displays to replace cathode-ray tubes in modern on-board aviation displays.
