Abstract

Abstract

To implement the high resolution imaging of a fast motion target in a longer distance, the key techniques of a multi-beam Fourier telescopy are preliminarily analyzed in this paper. On the basis of the system composition, the key techniques in optical sub-system, mechanical sub-system, electrical sub-system and software sub-system are discussed separately. In optical subsystem, the key techniques are focused on the main specifications of laser sources, phase detection elements, acousto-optic frequency shifters and opto-electric tubes; and in mechanical sub-system, it is pointed out that the directing and tracking of the telescopy, fast-switch of beams and supporting structure of primary mirror should be paid more attention. Furthermore, the electrical sub-system emphasizes the synchronization control, electromagnetic shielding and power distribution and the software subsystem lays the stress on the fast switch of beams, synchronization of changing of locations and angles and image restoration. The analysis and discuss in this paper will be provide a reference for the design of multi-beam Fourier telescopy.
