Abstract
A video projection system with at least one light source which can be controlled in intensity and generates at least one light bundle and with a deflecting device which deflects the light bundle sequentially to produce picture points of a video picture on a screen by picture and line scanning has two component groups, the first of which contains at least one light source and has a light output from which at least one light bundle exits, while the second component group contains the deflecting device and has a light input through which a light bundle can be imaged into the deflecting device. Further, a light transmission device is provided which enables the light output of the first component group to be optically connected with the light input of the second component group.
