Abstract: The development course of stabilized sight technology in helicopters is summarized. Base on the latest development of optoelectronic technology, DAS, image fusion technology, coarse/fine combination two-level stabilization, high-performance photoelectric sensor and directional infrared countermeasure system are analyzed; furthermore, the feasibility of these technologies applied in the airborne stabilized sight system is demonstrated. Some suggestions are proposed for the development of the stabilized sight system on helicopters and the application of the new technologies.
