Paper Abstract

In this paper, the feasibility of a sCMOS camera for astrometric exoplanet detection space mission was evaluated and the evaluation methods were also studied. A 2k x 2k single-chip sCMOS camera was installed on the metrology testbed for the space mission. The pixel size of the detector is 11μm, corresponding to 1.86 arcsec on the focal plane. The sCMOS camera runs with a electronic rolling shutter. We tested the performance of the camera in detail, including the gain, linearity, readout noise, dark current, pixel response non-uniformity, etc.. The data acquisition performance for the pseudo-star and the interference fringes are also studied.
