|Description:|| On Thu 29 Sep 2017, 15 students following the course Basic Detection Techniques (BDT) visited the Optical & IR group at NOVA-ASTRON for a labs session. In 4 groups the students worked on 4 experiments determining the wavefront error of an individual test sample using 4 different wavefront sensing techniques:|
- an optical test plate
- a Shack-Hartmann wavefront sensor
- a laser interferometer
- a Foucault knife-edge test
We experienced an enjoyable day, with great enthusiasm, pleasant interaction, good working spirit and look forward receiving great reports!
Thanks to Rik ter Horst, Annemieke Janssen, Joost van den Born, Ronald Roelfsema, and Eddy Elswijk for their help with the experiments, and Ramon Navarro and Albert-Jan Boonstra for the guided tours.
