Spatial light modulators are the limited component of optical signal processors. Electronic modulators, including liquid crystals and magento-optic modulators, are expensive, low resolution, and slow. The optical disk offers high resolution at moderate cost. The "pixel" size is on the order of one micron. The total system works to this accuracy by using an active feedback controlled system for ali ...

We propose a system to determine object attitude from special video imagery taken from two locations, with an image analysis system based on the Fourier Transform, which provides the spatial power spectrum of the image. The Fourier transform of an image represents the information in terms of angles and spatial frequencies. In this case we are interested only in the angles. The transform of a mis ...

This sponsoring agency has defined the need for a six degree-or-freedom (6DOF) magnetically levitated (maglev) test platform to be used for vibration analysis. The intended payload can range in mass from 1Kg to 1000kg and i size up to one meter by one meter at the base. Peak linear acceleration of 5 g's and strokes of 25 mm (peak-peak) are required. The platform should also be capable of simult ...

Thermal control of spacecraft is accomplished through the optical and thermal properties of the eternal surfaces of the vehicle. The use of thermal control coatings or second surface mirrors on these surfaces ar common methods for managing the overall thermal environment of spacecraft. The proposed low solar absorbance ( ) high emittance ( ET ) thermal control (TC) coating(s) shall be developed ...

BRC and its Consulting Partner Murray State University (MSU) are proposing an innovative approach to the near real-time generation of environmental effects such as dust, smoke, fog, rain and haze based upon an Auto-Regressive Moving Average (ARMA) technique that has been proven to provide realistic renderings in its simplest form. This technique creates 'Fractal-Like' complexity through the use of ...

BONN Corporation (BONN) has chosen to concentrate on a methodology that computes an optimal target search in near-real-time, with the capability of accommodating user-definable optimality based upon time / pathlength, probability of target detection target value, and survivability in a dense threat environment. This methodology will be extensible to address multiple airborne platforms and multipl ...

Objective is to develop the preliminary design and existing component modification required to integrate a 3-10 kw generator assembly using the newly patented new bold Turbo Rotary Powered Diesel Engine with a VSCF alternator that will have minimal 3 kw, 120 Vac, 50/60 Hz, 3 Phase power output up to 10 Kw, 120 Vac, 50/60 Hz, 3 phase output (depending ont he load requirement) in a lightweight compo ...

An innovative approach is proposed for the development of a low cost Air Turbo Rocket (ATR) propulsion system by using Off-the-Shelf (OTS) component technology. The proposed ATR propulsion system will be capable of delivering up to 500 lbf boost thrust and 265 lbf of fully throttlable sustained thrust with a 10-1 turndown ratio. All propulsion module integration requirements will be focused toward ...
