Optical design of head-up displays using CAD-compatible freeform surfaces
12.03.2009 - Photonik international 1/2009 | [ deutsche Version lesen ]
Head-up displays in automobiles offer a higher level of safety, driving comfort and an enhancement of prestige as well as feeding a passion for engineering. A critical component in designing head-up displays is the imaging mirror, which is typically designed as an optical freeform surface. This article will introduce the design methods and results and also emphasize that the freeform surface can be described already in the design process in such a way that an export into custom CAD systems is easily possible without risking any severe performance.
