Optical design of head-up displays using CAD-compatible freeform surfaces
نویسنده
چکیده
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.

Strategy to obtain initial configurations for free form reflectors design
A strategy to obtain sets of initial configuration to design freeform reflector surfaces is presented. This strategy brings the initial configuration of the reflector surface using a collection of elemental facets defined by Bezier surfaces and able to face the optimization process of the illumination system. The purpose of this communication is to provide initial configurations to obtain a set...

متن کاملTool Path Generation for Milling of Free Form Surfaces With Feedrate Scheduling
The use of freeform (sculptured) surfaces in the product design process is accelerating at an exponential rate driven by functional as well as esthetics demands. CAD/CAM software is a must in their design and manufacture. While the geometric aspects of the design are relatively wellcovered, issues still remain when it comes to the actual manufacture of freeform surfaces. The major issues are re...
متن کاملFiducial-Aided Robust Positioning of Optical Freeform Surfaces
Form characterization of a machined optical freeform surface demands accurate alignment of the sampled measured data points on the machined surface, and they are compared with the designed geometry of the surface through positioning. In this paper, a fiducial-aided robust positioning method (FAPM) is developed which attempts to evaluate freeform surfaces with high efficiency and precision. The ...
متن کاملFabrication of Freeform Optics
Freeform surfaces on optical components have become an important design tool for optical designers. Non-rotationally symmetric optical surfaces have made solving complex optical problems easier. The manufacturing and testing of these surfaces has been the technical hurdle in freeform optic’s wide-spread use. Computer Numerically Controlled (CNC) optics manufacturing technology has made the fabr...
