Paper Abstract
This paper reviews the recent laboratory results we have obtained on the demonstration of a cophasing algorithm
based on the chromatic phase diversity method. The SIRIUS testbed was initially dedicated to the demonstration
of the direct imaging capabilities of arrays of telescope. We have developed and numerically modeled a piston
sensor based on the chromatic dependance of the spectral density phase. This method allows a global cophasing
of the array over a capture range of many wavelengths aiming at improving the robustness of the method.
