Study of the correlation between interferometric tests, force field measurement, modelling, and as built characteristics of the ELT M1 segments during polishing

Based on force field tests and actual data acquired during system tests at REOSC (French company polishing the segments of the Extremely Large Telescope primary mirror M1), the goal of the internship will be to model the segment shape and to compare and correlate the model with the shape measured during interferometric tests.
