dc.description.abstract	Differential optical transfer function (dOTF) is a model-independent image-based wavefront sensor for measuring the complex field. This sensor-less wavefront sensing technique is efficient for precise non-common path aberrations (NCPA) measurement and the phasing of segmented telescopes. In this communication, we report on an initial exploration of the dOTF method with the SPEED facility for NCPA and cophasing optics application	en_US
