  • Omnidirectional light
    Patent number: 5126923
    Abstract: Intense illumination is cast omnidirectionally by a single light source that directs a ligth beam onto a pair of mirrors rotating hundreds of revolutions per second. The mirrors are mounted in an "X" configuration and are thus vibration-free. The light beam is split in half and directed in opposite directions by the mirrors to enable the mirrors to rotate at half the speed of single mirror devices. The light source may be offset from the axis of rotation of the mirrors to shroud preselected areas from illumination.
