August 2023: SCC phasing sensor first smile

Details

SCC gamma smiley

From the left to the right: ASM (active segmented mirror) representation combining the offset map (NCPA correction) and a smiley face by poking 8 segments of the same piston value, phase measurement using the SCC-PS (γ = 40) and phase measurement using the SCC-PS (γ = 50), where DIT and NDIT are identical. These are initial measurements, work in progress.
