摘要

为了消除成像视场外回波对条纹场扫描成像（又称为傅立叶望远镜或者相干场成像）的可能影响，本文从理论上分析回波引起重构混叠的主要原因，并针对不同的应用场合提出对应的最佳解决方案。本文通过计算机仿真手段详细研究不同照明区域回波对成像的影响，仔细分析增加短基线方案对重构模糊的改善效果。仿真结果表明：三光束（同时发射的最多光束）重叠区域的回波对重构结果有最严重影响；增加短基线可以消除图像混叠，单臂增加一个短基线则能使图像质量明显改善，对应的斯托里尔比（Strehl ratio）从0.49上升到0.59；且单臂增加基线数越多，则重构图像细节就越丰富。本文所提出的消除成像视场外回波影响的几种方案对于条纹场扫描成像系统在不同领域的应用均具有重要的借鉴价值。

Abstract

In order to eliminate the effect of echo outside the field of view (FOV) on fringes scanning imaging (also known as Fourier telescope or coherent field imaging)

this paper analysed in theory the main factors of reconstruction overlap caused by echo

and provided the best solutions to different application scenes. This paper studied in detail the effect of echo from different illumination zones on imaging by means of computer simulation and also analysed in detail the improving effects of the scheme of adding short baselines on reconstruction blur. The results of simulation show that the echo from three beam (the largest number of beams transmitted simultaneously) overlap zone has the most serious effect on reconstruction results and that adding short baselines can eliminate image overlap and also that the more short baselines are added

the more distinct details can be got(one short baseline can promote the Strehl ratio from 0.49 to 0.59). The schemes of eliminating effect of echo outside the FOV provided by this paper could be useful to the concrete implement of fringes scanning imaging in different application fields.
