Paper Abstract
CMOS is a good candidate tracking detector for satellite optical communications systems with outstanding feature of
sub-window for the development of APS (Active Pixel Sensor) technology. For inter-satellite optical communications
it is critical to estimate the direction of incident laser beam precisely by measuring the centroid position of incident beam
spot. The presence of detector noise results in measurement error, which degrades the tracking performance of systems.
In this research, the measurement error of CMOS is derived taking consideration of detector noise. It is shown that the
measurement error depends on pixel noise, size of the tracking sub-window (pixels number), intensity of incident laser
beam, relative size of beam spot. The influences of these factors are analyzed by numerical simulation. We hope the
results obtained in this research will be helpful in the design of CMOS detector satellite optical communications systems.
