| 摘要 |
The invention relates to an image projector with at least one projection bea m that is controlled in raster mode and in calligraphic mode, for displaying a raster part and a calligraphic part of a total image that is projected onto a display. The aim of the invention is to achieve greater brightness and contrast for projection in non-darkened rooms. To this end, the at least one projection beam is a laser beam (19) that is divided into two linearly polarised partial beams (21, 21'). The two partial beams (21, 21') are separately modulated and deflected in such a way that one partial beam (21') determines the raster part and the other partial beam determines the calligraphic part. The two partial beams (21, 21') are projected onto the display at the same time. They may be optically superposed beforehand.</SDOA B>
