Speckle Image Reconstruction of Solar Features.
Abstract
The hardware and software required to demonstrate and evaluate the speckle imaging process for use on solar features have been developed and tested. A video speckle camera has been designed, constructed, and successfully used to record data for a wide variety of astronomical objects, including solar features. The problems associated with recovering images from speckle data have been explored extensively. Particular attention has been given to identifying and correcting effects due to noise bias and edges in images reconstructed from real as well as simulated data. The principles involved in imaging solar features at improved resolution by means of speckle techniques have been delineated, and sample images recovered from a variety of test data. (Author)
