Abstract
An illumination optical arrangement comprises light source means emitting a coherent light beam, and means for forming a substantially incoherent light source from the coherent light beam. The incoherent light source forming means includes means for periodically deflecting the coherent light beam and scanning a predetermined scanning area by the coherent light beam, and optical means for forming a plurality of optical paths for directing the coherent light beam passed through the predetermined scanning area to a plurality of different secondary scanning areas. Each of the plurality of secondary scanning areas is scanned by the periodically deflected coherent light beam.
