Utilizing optical microscanning technique and sub-pixel imaging processing to achieve sub-pixel imaging system is an important technical method to improve the spatial resolution of optoelectronic imaging system. By analyzing the sub-pixel imaging and microscanning reconstruction of two-dimension staring focal plane detector, the paper presents a kind of sub-pixel processing algorithm based on two-dimension microscanning and solves the margin demarcation problems. By analyzing the result of simulation, this algorithm is good for achieving sub-pixel imaging and easy to achieve real-time processing because of small processing load. The processing algorithm can be widely used in the field of visible light and infrared imaging system. Application of this processing algorithm will enormously enhance staring thermal imaging system's performance.
