speckle imaging

(method of combining short-term images to yield better resolution)

Speckle imaging is a means of producing high resolution images in the face of atmospheric distortion from seeing issues. Numerous images are taken at relatively short exposures and through image processing, an image is produced with detail likely to match the image without the distortion. A straight-forward process called shift-and-add aka image stacking can be used, or a type of interferometry called speckle masking
