The second user control interface of the bench is dedicated to the co-phasing arm of the bench. The control interface is developed under Matlab, and allows calibration, operation and exploitation of the SCC-PS (Self-Coherent Camera Phasing Sensor). The interface controls all the hardware of the optical arm of the SPEED bench (motors, camera) and automatized the cophasing process (interaction matrix, signal sanity check, open-loop, close-loop, focal plane mask centering, SCC data post-processing treatment, etc.).
