<P>46The Military Engineer ? July-August ? 2010 Improving UAVs Using Holographic Adaptive Optics U.S. Air Force Of?ce of Scienti?c Re- search (AFOSR)-supported holographic, adaptive, optics research may help trans- form software into computer-free elec- tronics for unmanned aerial vehicles (UAV), high-energy lasers and free-space optical communications that will enable each to run faster and more ef?ciently. Geoff Andersen, Ph.D., Senior Research- er at the Laser and Optics Research Center at the U.S. Air Force Academy in Colorado Springs, Colo., is leading a team of re- searchers who have successfully demon- strated the latest type of adaptive optics, which incorporate holograms. The con- ventional, computer-based technology that has been in use for over two decades is no longer suitable for some military ap- plications—including UAVs—because of required calculations and high comput- ing costs. The new technology will be able to be incorporated on UAVs because it is very compact and lightweight. We will see hugely-improved images from these new surveillance platforms that holographic adaptive optics will make possible, said Dr. Andersen. The current system for UAV imagery, lasers and optics is computer software driven, but the next phase is to replace that with an electronics system called High Altitude Large Optics HALOS. Such a system would be orders of magnitude faster than anything else available, while being much more compact and lightweight. It is hoped that HALOS will become the standard in adaptive optics of the future. It may also create entirely new markets for sharper telescopes and camera images that will be used for military purposes.

Many of these crashes could have been prevented and lives saved by the Synthetic Automotive Vehi- cle Environments (SAVE) project. SAVE uses new simulator technologies devel- oped by ERDC and hands-on driving in- struction to teach soldiers and civilians improved driving skills in off-road or austere environments. The U.S. relies primarily on technolo- gy and improved roadways and vehicles to reduce crashes, but this is not the case for soldiers in deployed environments. Enhanced driving techniques often overlook skills required to control ve- hicles safely when unexpected hazards occur on unimproved, narrow, gravel, or dirt roads. The goal of SAVE training is to teach those skills. During initial training, students spend time in a new simulator capable of mov- ing in reaction to simulated road surfaces and driver inputs. This provides a very realistic sense of how driver actions con- trol a vehicle in challenging situations. The simulator combines commercially- available hardware with ERDC-developed software to virtually recreate any type of scenario in any environment. These tools allow students to learn key vehicle control concepts like eye place- ment, effective braking and acceleration, vehicle weight transfer and rollover avoid- ance. Through repetition, students gain the skills that make proper motions and reactions automatic. A critical element of the simulator is the understanding of high speed-loose sur- face vehicle-tire interface and terrain dy- namics. This is put to the test during the Beta phase of training, as students take Technology News (continued)</p> <UL><LI><a
