PROJECTION HEAD FOR A LASER PROJECTOR

摘要

A projection head is provided that has a fiber output coupling. A position of a point of intersection is able to be set between the light beams and thereby it is possible to position the point of intersection on the polygon facets. As a result, lower losses of light occur and edge discolourations during projection are reduced. The distance between the fibres can be chosen to be small (approximately 25-125 μm). It now also becomes possible to incorporate more than two fibres, as a result of which a plurality of lines can be scanned simultaneously.

主权项

1. A projection head for a laser projector, comprising:
a light source emitting a light beam; a polygon facet mirror; and an outcoupling unit arranged downstream of fibers, the fibers being slightly spaced apart and collimated beams being crossed by the outcoupling unit at the polygon facet mirror.
