Windscreen for a collimating driving system

摘要

A windscreen (130) for a collimating driving system is formed such that its opposing large external surfaces (138 and 140) are not parallel. As a consequence, an image coming from a display source (14), and reflected by a large external surface (138) of the windscreen is superimposed on the image reflected by the opposite large external surface (140) of the windscreen (130). <IMAGE>
