| 英文摘要 | In recent years, sparse-optical-synthetic-aperture telescope has emerged as an important developing trend for large-scale telescope, where the correction of piston error among different Sub-apertures plays an important role for achieving high resolution. The 2 pi ambiguity effect is the most important aspect of piston error's influences upon system's far-field intensity, which was theoretically analyzed at first. Then the bi-sub-aperture system was taken as an example to test the correctness of the theoretical model through distributions of the system's far-field intensity. In addition, a theoretical proof was made to get some important properties of piston errors within such kind of system. From the results, it is shown that the 2 pi ambiguity comes along with any piston error in the system, and this effect stands independent for different piston errors between different pair of sub-apertures. The derivation also provides effective theoretical model for related concerns within such kind of system. (C) 2013 Elsevier GmbH. All rights reserved. |
