Flat screen initiated by laser beam with focussed beam directed onto facetted mirror to deflect beam onto screen

摘要

Laser light is transmitted by laser light emitter (4) onto mirror (2) with facetted tracks, in horizontal direction. The mirror (2) has facet-like tracks having flanks at specific angle, so beam is reflected past lens or convex mirror (6) and is deflected orthogonal to rear side of screen.
