Field(s) of activity for the internship

You can choose among the following topics:

1) Topic 1: Use of machine learning in optical design
 
Define a database of potential architectural solutions based on high level requirements (spectral range, F#, field of view, etc.) and develop/use AI tools to define potential starting points. Explore then the possibility of reinforcement learning techniques to optimise the solution.

2) Topic 2: Increase capabilities of open source optical design software (e.g. Optiland)

Explore the possibility to expand the software e.g. a) starting the implementation of a non sequential raytracing, b) implementing the possibility to introduce mechanical elements, or c) improving straylight analysis capabilities (e.g. ghost analysis, semi-analytical calculations similar to an existing ESA tool called ‘Straylux’).

3) Topic 3: Define a simulator for the Vigil HI instrument

The simulator should contain the specific scene definition (F+K corona, planets, stars, coronal mass ejections), introduce instrumental effects (noise, straylight, etc.). Based on the simulator, detection methods for the coronal mass ejections should be investigated.
