摘要	Compared to traditional scientific CCD cameras in which the exposure of each pixel starts and ends synchronously, rolling shutter sCMOS cameras have recently emerged and operate based on an asynchronous start and end time, but with the same exposure period. For space debris observation, it is necessary to evaluate the effect on the measurement accuracy due to the asynchronous exposure among the sCOMS pixels. Firstly, the working sequence and max delay of certain sCMOS cameras were tested, and a correction formula was obtained. Subsequently, several laser satellites were selected as observation targets to test the astronomic positioning accuracy of space debris under two typical observation modes. The differences before and after exposure with non-synchronization correction were then compared. The experimental results indicate that the working sequence of a rolling shutter sCMOS camera is consistent with a theoretical device, and the maximum delay in the border row is 10 ms. The results also indicate that the internal accord accuracy of the staller position is better than 2 arcsec, and better than 3 arcsec for the precision of object astronomic positioning. Rolling shutter sCMOS cameras can be used for space debris observation with high-precision position measurements. 2018, Science Press. All right reserved.
