Phase estimation:
- Optimized for long exposure time (10s seconds to mesure 1nm level-EPICS case)
- Simple set-up with Lyot and phase mask coronagraph
- To be coupled with IFS because of chromatism (or need more advancedestimator)
- Deeper study on-going (closed loop, chromatism,…)
- Coupling with planet detection to be studied in more details (especially forthe long exposure time case)
- Need more laboratory test
