Journal of Astronomical Telescopes Instruments and Systems, Society of Photo-optical Instrumentation Engineers, 2020, 6 (4), pp.040501. ⟨10.1117/1.JATIS.6.4.040501⟩

Focal plane wavefront sensing is an appealing technique to cophase multiple aperture telescopes. Phase diversity, operable with any aperture configuration or source extension, generally suffers from high computing load. In this Letter, we introduce,
