散斑成像 Speckle imaging

（重定向自Speckle Interferometry）

大气层存在时典型的短时间曝光联星影像（影像中为左摄提三）。影像中恒星应该是一个点状，但是大气层的存在让两颗恒星成像是班点状（一个在左上方，其他的在右下方）。这些班点会让观测者较不易分辨影像中的恒星，这是因为使用的相机像素较粗糙。斑点会在恒星影像周围快速移动，使恒星在影像中看起来像一个模糊的斑点。拍摄该影像使用的望远镜直径约7r₀（望远镜直径小于 r₀ 时，影像分辨率由艾里斑大小决定，否则是由大气层状态而定）
慢动作散斑成像负片影片，为使用高倍率望远镜观册恒星的状况。该望远镜的直径约7r₀。请注意单一恒星影像如何分裂为多个斑点，这完全是因为大气层扰动所造成。散斑成像技术就是要重建未被大气层扰动影响的恒星影像。该影片中也可见到望远镜镇动造成的效应。

Speckle imaging 散斑成像

（重定向自Speckle Interferometry）

Typical short-exposure image of a binary star (Zeta Bootis in this case) as seen through atmospheric seeing. Each star should appear as a single point, but the atmosphere causes the images of the two stars to break up into two patterns of speckles (one pattern above left, the other below right). The speckles are a little difficult to make out in this image due to the coarse pixel size on the camera used. The speckles move around rapidly, so that each star appears as a single fuzzy blob in long exposure images. The telescope used had a diameter of about 7r₀ (see definition of r₀ under astronomical seeing, and the example simulated image through a 7r₀ telescope).
