A laser tracking system was developed.The transmiter of the system is a semiconductor laser with a wavelength of 905 nm.The detector of the system is a quadrant photodetector.Experiments were made with the system.The target was 8 meters away form the tested system.The accuracy of tracking is ± 2.5 mrad.The feature of this system is compact,accurate,stable,easy to use.In some near range application,it has many advantages over the traditional tracking system.
