  • On the basis of the demands of high resolution in imaging technologies of developing engineering practices, the imaging principles of an optical synthetic aperture and the advantages in improving the resolution of image was discussed in this paper. The domestic and foreign research results and the exciting technical difficulties in the relevant research fields also were demonstrated. In the current conditions of processing and testing alignment, the imaging experiment of two sub-aperture telescope was designed. From theory of geometrical optics, using Fizeau-type multi-aperture telescope, the experimental possibility of Fizeau-type synthetic aperture was investigated. The adjustment accuracy of the key components in the synthetic imaging system was researched, which ensures that the system can make an image completely. In the experiments, the fine tuning mechanism with a designed resolution less than 0.03 mm ensures that the system can obtain a clear image, and the precision piezoelectric linear drive system with a resolution 0.05 m guarantees the synchronization of two beams' phases. The results show that the foundation of the designed experiment is feasible, and the system can offer the exact resolution values. This research makes a useful basis for the synthetic aperture imaging system, and has important potential in practices.
