Image projector
Abstract:
An image projector includes an illumination arrangement with a number of illumination sources and a tilt-mirror assembly, all operating under control of a controller. An optical arrangement directs illumination from the illumination sources towards the mirror and on to an image plane. A collimating arrangement collimates the illumination from the image plane to generate a collimated image directed to an exit stop. The controller (830) modulates an intensity of each of the illumination sources (808) synchronously with tilt motion of the mirror (814) according to the content of the digital image. In certain implementations, the illumination sources (808) are spaced apart. Although the tilt motion brings each illumination source to scans across only part of a dimension of the field of view, all of the illumination sources together scans across the entirety of the one dimension.
