Abstract

Astronomers have long applied post detection processing to achieve diffraction limited images through atmospheric turbulence. We investigate the extension of these methods to the daylight astronomy problem, and to the problem of satellite imaging. After establishing radiometry and detection limits, we analyze white light speckle imaging in the stringent satellite imaging case. We then analyze the speckle holography (wavefront sensor deconvolution) imaging technique and compare these two methods. We also simulate images to compare performances, and present astronomical data obtained during daylight conditions for both methods.
