Estimating differential pistons for the Extremely Large Telescope using focal plane imaging and a residual network
P. Janin-Potiron, M. Gray, B. Neichel +6
As the Extremely Large Telescope (ELT) approaches operational status, optimising its imaging performance is critical. A differential piston, arising from either the adaptive optics…
