Abstract
An optical system comprising a segmented optical element comprising a plurality of segments disposed adjacent each other to define a pupil, wherein one or more of the plurality of segments comprises a pair of curved edges, wherein the segmented optical element is arranged such that a curved gap is defined between adjacent segments.
Claims20
An optical system comprising:
- a segmented optical element comprising a plurality of segments disposed adjacent each other to define a pupil,
- wherein one or more of the plurality of segments comprises a reflective surface or optical power transmissive lens,
- wherein one or more of the plurality of segments comprises at least a pair of curved edges to facilitate nesting of adjacent segments,
- wherein the optical element is arranged such that a curved gap is defined between adjacent segments.
1 more element
A system comprising:
- a segmented optical element comprising a plurality of segments disposed adjacent each other to define a pupil, wherein each of the segments comprises curved sides to nest the segments one adjacent to the other across the segmented optical element such that the image plane diffraction noise is minimized by disrupting the diffraction pattern and creating a nearly uniform background a cross the image plane.
