US Patent Awarded to Dr. Geoff Andersen

Sep 2008
Dr. Geoff Andersen, a laser physicist at the United States Air Force Academy’s Laser and Optics Center in Colorado, has been awarded a US patent for his development of a holographic image corrector. Dr. Andersen devised a type of microscope that uses an inexpensive, low quality objective lens of any size and combines it with a specially designed hologram to compensate for aberrations and to provide clear images. The device can be designed to have a wider field of view than normal microscopes and it allows researchers to see more of the object. With simple modifications, it can be configured to provide three-dimensional contour mapping so that it can be used in viewing and projection modes. The patent was filed jointly with the Air Force; Dr. Andersen built and tested it with cadet physics research majors. This is Dr. Andersen’s third patent since commencing at the Academy 12 years ago.


GLOSSARY
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
