Holographic Adaptive Optics Improve UAVs
ARLINGTON, Va., May 5, 2010 — Holographic adaptive optics could help transform software into computer-free electronics for more efficient unmanned aerial vehicles (UAVs), high-energy lasers and free-space optical communications.

Dr. Geoff Andersen, senior researcher at the Laser and Optics Research Center at the United States Air Force Academy in Colorado Springs, is leading a team of researchers who have successfully demonstrated the latest new type of adaptive optics, which incorporate holograms. The conventional, computer-based technology has been in use for over two decades, but is not suitable to some military applications, including UAVs because of its required calculations and high computing costs.
The new technology will be able to be incorporated on unmanned aerial vehicles 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 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)," he said. "Such a system would be orders of magnitude faster than anything else available, while being much more compact and lightweight."
The researchers hope 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.
The research is supported by Air Force Office of Scientific Research.

- adaptive optics
- Optical components or assemblies whose performance is monitored and controlled so as to compensate for aberrations, static or dynamic perturbations such as thermal, mechanical and acoustical disturbances, or to adapt to changing conditions, needs or missions. The most familiar example is the "rubber mirror,'' whose surface shape, and thus reflective qualities, can be controlled by electromechanical means. See also active optics; phase conjugation.
- An interference pattern that is recorded on a high-resolution plate, the two interfering beams formed by a coherent beam from a laser and light scattered by an object. If after processing, the plate is viewed correctly by monochromatic light, a three-dimensional image of the object is seen.
