Abstract: In a digital image projector, a deflector array, for deflecting light in a chosen direction towards the projection surface, houses a digital image generator, such as a digital micro-mirror device (DMD). While light passes through the deflector array, the image generator receives a digital image signal and modulates the light, producing the image beam. In a double-mirror array, the image generator may be located after both mirrors, or between the two mirrors. Where the image generator is a DMD, one of the mirrors is replaced by the DMD itself.

Abstract: In order to move spatially the projection beam from a video or graphics projector, the projection beam which emerges from a light source and is guided via and/or through an optoelectronic image generator and through a projection lens is deflected by means of at least one mirror which can be pivotably displaced about two axes, an X-axis extending in the direction of incidence of the projection beam and a transverse Y-axis. In order to attain perfect correction of the image distortion caused by rotation in spite of the rapid movement of the mirror, the images to be projected from the image generator are further rotated when the mirror is pivotably adjusted about the X-axis in forced coupling with the pivotal adjustment of the mirror in order to compensate any image distortion occurring.
