Abstract
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.
Claims20
An optical pattern generator comprising two or more multi-faceted rotating optical elements, each multi-faceted rotating optical element having a rotational axis and a plurality of facets that rotate around the rotational axis;
- wherein the rotating optical elements have corresponding facets that rotate through an optical axis in synchronization and at least two of the corresponding facets cause unwanted optical effects that occur for each facet acting alone but that counteract each other when the facets are acting together.
A method for using an optical pattern generator comprising rotating a plurality of facets around a rotational axis of each of two or more multi-faceted rotating optical elements;
- wherein the rotating optical elements have corresponding facets that rotate through an optical axis in synchronization and at least two of the corresponding facets cause unwanted optical effects that occur for each facet acting alone but that counteract each other when the facets are acting together.
An optical pattern generator comprising two or more multi-faceted rotating means, each multi-faceted rotating means having a rotational axis and a plurality of facets that rotate around the rotational axis;
- wherein the rotating means have corresponding facets that rotate through an optical axis in synchronization and at least two of the corresponding facets cause unwanted optical effects that occur for each facet acting alone but that counteract each other when the facets are acting together.
