The performance of Photoelectricity Trackers is usually required to be tested in the process of developing or repairing. A simple revolving photo-electricity target is realized based on a collimator, and it can be used to test the Photoelectricity Trackers’ performance. The photo-electricity target is mobile, and convenient to test lots kind of Photoelectricity Trackers. The testing results show that the orientation angle error (average square root value) of the photo-electricity target is 9.8 , and the pitch angle error is 9.1 . It is suitable for testing common Photoelectricity Trackers.
