Asymmetric Lens Design Using Bicubic Splines: Application to the Color TV Lighthouse

Not Accessible

Your library or personal account may give you access

Abstract

Any two-dimensional interpolation scheme which has continuous derivatives may be used to represent an optical surface for ray-tracing purposes. We present bicubic splines in their application to the design of asymmetric surfaces. An as example of a problem requiring an asymmetric system, we analyze the design problems of a color TV lighthouse lens.
