Characterizing the fundamental response and operational parameters of a deformable mirror is a critical first step in the design of an adaptive optics system. This paper describes the characterization and training of a piezoelectric deformable mirror

We consider the problem introduced by rotation in the use of early-type stars as calibrators for optical interferometry. These objects have high surface brightnesses and hence are relatively bright, even with small angular diameters. However, rotatio

A novel concept is described for optical interrogation, communication, and navigation between pursuer and target spacecraft platforms. The technique uses a gimbaled laser source on the pursuer spacecraft and an array of eight solid-state, multiple qu

An experiment is described in which the performance of the Naval Space Command Fence Receiver Suite is evaluated using satellite laser ranging. Fence measurement accuracy and precision is presently assessed based on cataloged orbits,which are notsufe

Theoretical and experimental results are presented which demonstrate that slowly oscillating signals experience a temporal delay in photorefractive two beam coupling experiments. This delay corresponds to the response time of the signal. It is determ

Characterizing atmospheric turbulence through modeling dates back to the 1960's. For decades scientists have studied how to mitigate the effects of the atmospheric turbulence on communications and imaging systems, but learning how to use those proper
