The AFGL Image Reconstruction Program II Speckle Interferometry.

Abstract

Recent work indicates that large-telescope, optics-limited images are recoverable for objects as faint as +15 stellar magnitudes using a technique called speckle interferometry. This report presents a review of speckle interfeometry, including current status and results. Section 2 provides a background of the Fourier mathematics used in image processing and optical systems. Section 3 describes how the atmosphere degrades astronomical images and how speckle interferometry has been used to reciver high-resolution detail. Section 4 describes new work to recover actual optics-limited images, and compares active optics systems with speckle interferometry. (Author)
