Opt Lett 36:4731-3. 2011..Applications may range from astronomy to microscopy. For example, the centroid and angular extent of an unresolved collection of incoherent point sources is revealed...
- Optical vortex coronagraphy with an elliptical apertureGarreth J Ruane
Chester F Carlson Center for Imaging Science, Rochester Institute of Technology, 54 Lomb Memorial Dr, Rochester, NY 14623, USA
Appl Opt 52:171-6. 2013..This design incorporates an elliptical subaperture rather than the conventional circular subaperture. We derive a new vortex phase mask that maintains the same theoretical contrast of a circularly symmetric vortex coronagraph...
