electric field reconstruction in the image plane of a high-contrast coronagraph using a set of pinholes around the lyot planeThe pair-wise estimation has been used now on various testbeds with different coronagraphs with the best contrast results to date. Pinholes estimate has been implemented and ready to be tested in closed loop correction. Pinholes estimate offers an independent method. We hope to improve the calibration process to gain better estimates.
