Optical pattern generator using a single rotating component

An optical pattern generator includes one or more multi-faceted rotating optical elements that introduce an offset that is rotation insensitive. The component that generates the offset is rotationally symmetric around the rotational axis of the optical element. Thus, as the optical element rotates,...

Summary:An optical pattern generator includes one or more multi-faceted rotating optical elements that introduce an offset that is rotation insensitive. The component that generates the offset is rotationally symmetric around the rotational axis of the optical element. Thus, as the optical element rotates, the effect of the offset component does not change. In addition, rotating optical elements may be designed to counteract unwanted optical effects of each other.
