Abstract

The invention relates to a video projection system that is provided with a laser that emits a laser beam. The laser beam is deflected onto the projection surface by means of a deflection unit. The projection surface contains luminous substances which generate light beams when the laser beam impinges, whereby said light beams have a predetermined wavelength. The light beams generated by the luminous substances are detected using a detection unit. The intensity of the laser beam is controlled according to desired video data and the detected light beams and by means of a control unit.
