We present here results of laboratory and field experiments using the OKO technologies membrane mirror as an adaptive optics device. The device can be operated at high temporal bandwidths from a low cost PC based control system. We have constructed a

We describe here a preliminary set of experiments to demonstrate the feasibility of laser illuminated imagery for remote surveillance from an airborne platform. Such an imaging sensor enhances the presently available sensor suite in that it provides

The performance of operational military E-O systems including imaging FLIRs, target designators, and laser rangefinders (LRF) is limited by atmospheric refractive- index turbulence. In locations subject to intense daytime heating and significant nigh

Nematic liquid crystals have been sued as phase retarders in adaptive optics system for more than 10 years. Liquid crystal spatial light modulators (SLMs) can be very useful both as controlled disturbances for characterizing adaptive optics systems,

Multi-segment liquid crystal spatial light modulators have received much attention recently for use as high-precision wavefront control devices for use in astronomical and non- astronomical applications. They act much like piston only segmented defor

It has been demonstrated both with computer simulation and field experiments that low order adaptive optics can improve the signal to noise ration in subsequent computer post- processing algorithms, especially when viewing an extended object. In this

Logicon RDA and Applied Technology Associates have supported PL/LIMI on various imaging experiments during the past years. We are currently supporting an adaptive optics experiment using a 349 actuator deformable mirror. We discuss the system require

Optical design of a compact adaptive optics system, to be mounted on the side of a large telescope, presents special problems. In particular the limited space requires fast optics. Signal to noise requirements for the wave-front sensor also require t

The utility of a blind deconvolution algorithm used in conjunction with the Knox-Thompson algorithm is demonstrated with day time observations of the MIR space station. 1. INTRODUCTION In previous work we discussed the idea of using a blind deconvolu
