We investigated the spatial structure of atmospheric turbulence at Maui Space Surveillance Site (MSSS) using a 3.6 m telescope and a spatial filtering receiver. This receiver simultaneously records four star images on one camera frame. The star image

The GEO Light Imaging National Testbed (GLINT) will use three laser beams producing simultaneous interference fringes to illuminate satellites in geosynchronous earth orbit (GEO). The reflected returns will be recorded using a large 4,000 m2 'light b

Using a large adaptive optical system designed for the correction of a visible wavelength laser, we report the results for the first known compensated laser illumination demonstration of an uncooperative low Earth orbit (LEO) satellite using an activ

We report on the design and fabrication of a high bandwidth interferometer suitable for real- time measurement of the figure of a deformable mirror. The design allows for measurement of mirror figure in terms of optical path differences (OPD) between

This paper describes a system capable of real-time wavefront reconstruction for a 512 subaperture shearing interferometer. The system was designed to interface with a 1536 channel (512 segment) deformable mirror for atmospheric compensation using an

Results from a benchtop experiment to demonstrate phase compensation using a 512 segment, 1500 degree-of-freedom adaptive optic system are presented. Atmospheric phase distortion is simulated by a static Kolmogorov spectrum aberration plate with r0 e
