Ultra-light materials are enabling for producing space based optical components and support structures. Heretofore, innovative design using existing materials has been the approach to produce lightweight optical systems. Graphite fiber, because of its lightweight, reinforced composites have been a material of frequent choice to produce space based optical components. A novel and unique new approac ...

The proposed work is to develop a whole-field measurement technique that iscapable of simultaneously sizing multiple transparent droplets on a plane fromscattered light features that are independent of laser beam intensity andobscuration. Light scattered by reflection and refraction from droplets immersedin a laser sheet is recorded holographically to yield the smallest possibleprobe volume and co ...

MetroLaser has demonstrated the feasibility of expediting the measurement of surfacevelocity profiles with laser Doppler vibrometers by two orders of magnitude overcommercial systems. This represents a significant breakthrough in the detection ofburied landmines with airborne acoustic methods as demonstrated by scientists at theUniversity of Mississippi.In Phase I we studied the technical feasibil ...

MetroLaser proposes to develop a holographic diagnostic instrument and associatedimage processing software for quantitative analysis of the response of windows toshock wave loading. The system will be useful in monitoring the window glass fromthe time the shock wave strikes until the resulting fragment field has propagatedseveral feet into the test chamber. Holography will be used to record all ...

Reliable and operationally simple methods that can be used in the field are needed for expeditious fatigue damage precursor detection. We have developed a strategy for constructing a laser-based sensor for creep or fatigue damage detection and monitoringin aerospace components. The sensor detects precursors to crack formation occurring as early as the first 10% of fatigue life and, therefore, can ...

This is a Phase 2 proposal to develop an instrument to simultaneously measure particle size, velocity, and concentration in applications characterized by a large size range and high particle concentration. The instrument will be based on the Pulse Displacement Technique whose feasibility was demonstrated during Phase 1. Experiments performed during Phase 1 demonstrated a high accuracy in meas ...

The objective of this proposal is to demonstrate the benefits of a computer controlled active damper suspension system based on a magnetorheological (MR) fluid controllable damper for off-road ground vehicles and that Rod Millen Special Vehicles (RMSV) hasthe expertise, equipment and facilities to develop an active MR fluid damper based suspension system for the HMMWV and other ground vehicles in ...

Atmospheric turbulence adversely affects imaging systems by causing a randomdistribution of the index of refraction of the air through which the lightpropagates. We show that tactical Army infrared sensing systems are not affected byturbulence in the same way as astronomical imaging systems, but the influence ofturbulence can still be quite strong. Rather, the shape of the point spread functiona ...

All phases of full-mission simulations (FMS) are supported by software tools except the most critical - planning. The use of Distributed Interactive Simulation (DIS) technology in the military materiel acquisition process and increasing complexity of DISwill make it harder to plan valid tests.. A FMS literature review and, interviews with FMS experts made it clear that a planning tool will add t ...

This Phase II SBIR Project will provide optimization framework and technology for Interoperable Message Passing Interface Technology, and the underlying Message Passing Interface Standard. This effort represents a challenge and Opportunity. With the emergence of cluster computing, there are many opportunities to connect diverse parallel programming Environments based on the MPI programming mo ...
