Poisson-Spot Intensity Reduction with a Partially-Transparent Petal-Shaped Optical Mask

摘要: The presence of a Poisson spot inside shadow region can best be described as the consequence constructive interference light waves diffracted on edge obstruction where its central position determined by symmetry object. More recently, elimination this has received attention in fields particle physics, high-energy lasers, astronomy, and lithography. desired level intensity suppression is dependent type source field application. In paper, we introduce novel, partially transparent petaled mask shape that suppresses bright up to ten orders magnitude at optical ranges, with potential powerful applications many above fields. optimization technique formulated design identify shapes having partial transparency only near petal tips.
