VP ASL-Astro Coronagraphy
Registration
The ASL-Coronagraphy experiment is part of the course "advanced physics lab" (VP, Vorgerückten-Praktikum), and registration for the experiment is similar to a standard VP experiment. After registration, the ASL supervisor at the institute will contact the students for having a first discussion and introduction into coronagraphy, a method for improving the imaging contrast allowing the observation of faint sources close to bright objects.
Aim of the experiment
The students will learn to setup an imaging optical bench used in coronagraphy, and control the active optics component, the SLM, demonstrating its power as a reprogrammable device for wavefront control.
Instrumentation
Students will make use of state-of-the-art Spatial Light Modulators (SLM) that allow to manipulate wavefront’s amplitude or phase as a function of spatial position. We will study these devices and their characteristics and conduct principle measurements of applied Fourier Optics.
