We evaluate a novel wavefront sensing technique using digital holography. This technique divides the aperture plane into multiple subapertures with a unique digital holographic image created in each subaperture. This reduces the complexity and allows

Self-referencing interferometer adaptive optics (SRI AO) provides innovative technologies for improving performance of free space laser communications. We provide an overview of the next generation SRI AO system and discuss results from system testin

Simulating the effects of atmospheric turbulence on optical imaging systems is an important aspect of understanding the performance of these systems. Simulations are particularly important for understanding the statistics of some adaptive-optics syst

A fundamental problem of adaptive-optics systems is the very narrow corrected field of view that can be obtained because turbulence is extended in altitude throughout the atmosphere. The correctable field of view is of the order of 5-10 µrad at visi

Over the past decade adaptive optics (AO) has proved its worth as AO systems have been used successfully on several telescopes to improve image resolution. As scientists and engineers push the technological state of the art in an effort to make bigge

We introduce adaptive optics as a technique to improve images taken by ground-based telescopes through a turbulent blurring atmosphere. Adaptive optics rapidly senses the wavefront distortion referenced to either a natural or laser guidestar, and the
