Abstract为了实现新真空太阳望远镜(NVST)多波段图像0.1″精度的视场匹配,提出了针孔光阑视场定标的方法,并在NVST光球TiO(705.8nm)通道和色球Hα(656.28nm)通道上进行了实验分析。采用11×11点阵的针孔阵列光阑,对两通道视场之间的旋转、放缩和平移关系进行了定标。通过仿射变换实现两通道太阳图像的高精度视场匹配,精度可达0.031″。虽然匹配残差在整个视场内(约为2′)存在不均匀性,视场边缘最大残差为0.076″。定标参数的数值会随着光学平台位置的变化而改变,造成了0.05″的视场匹配差异,但这些匹配差异都在分辨率要求的精度之内。对TiO通道和Hα通道实测数据的分析也证明了上述方法的精度估计。
