摘要
射电望远镜主反射面面形精度是影响望远镜性能最重要的因素之一,因此主反射面面形测量的研究和应用是评价和补偿天线性能的重要基础.本文梳理了经纬仪测量法、激光测量法、全息测量法、摄影测量法等主要的大型反射面天线主反射面的面形精度测量技术,并对每种测量方法的原理和应用案例进行了说明和总结,为QTT天线的主面测量技术提供参考.
The accuracy of the main reflector surface is one of the most significant factors influencing radio telescope performance.Thus, research on and application of main reflector surface measurement are an important foundation for evaluating andcompensating the antenna performance. In this review, theodolite measurement, laser measurement, holographicmeasurement, photogrammetry, and sensor measurement are assessed, and the principles and application cases of eachmeasurement method are explained and summarized to offer a reference for the main surface measurement technology ofQTT.
