We present an experimental study of photon statistics for high-contrast imaging with the Microwave Kinetic Inductance Detector (MKID) Exoplanet Camera (MEC) located behind Subaru Coronagraphic Extreme Adaptive Optics System (SCExAO) at Telescope. show that MEC measures expected distributions both on-axis companion intensity and off-axis which manifests as quasi-static speckles in image plane cu...
