Coherent and Incoherent Light Separation Using Image Plane Vortex Phase Masks

Abstract

We consider the application of a modified optical vortex coronagraph as a transmissometer. We find, through theory and simulation, that the rejection of scattered light benefits from increasing the charge number of the vortex masks in the image plane, and that a combination of vortex mask and binary pinhole can outperform the pinhole alone.
