High-Resolution Optical Systems for High-Definition Television

Jack Dawson

HDTV camera lenses and prism systems must be capable of twice the resolution of conventional lenses and optics used for today's TV standards, and produce 35mm film color quality on a large screen with a minimum aspect ratio of 5:3. — The large picture size and aspect ratio require a much higher degree of sharpness to attain the color fidelity. Resolution, brightness and contrast all contribute to the sharpness of the picture. — The discussion presents the most important design considerations for a zoom lens and prism system that produce consistently high quality pictures regardless of F stop and focal length.
