Irradiance at Lyot Stop Plane (Model Image)Lyot stops are used to block stray light that is diffracted off of apertures and obscurations. These stops must be large enough to block unwanted stray light; but if they are too large they also block the desired signal. The ASAP Gaussian Beam decomposition algorithm calculates the diffracted... |
