Title: Byong H Ahn: Innovator in Optical Power Limiting Technologies
Introduction
Byong H Ahn is a notable inventor based in Springfield, VA (US), recognized for his contributions to optical power limiting technologies. He holds a total of 4 patents, showcasing his innovative approach to protecting sensitive infrared sensors from high-power laser threats.
Latest Patents
Among his latest inventions is the Optical Power Switch, which provides a protective device for sensitive infrared sensors such as Forward Looking Infrared imagers (FLIRs). This invention combines materials with higher order susceptibilities to electric polarization with low energy optical limiters like chalcogenide glass and vanadium dioxide, which respond reversibly to infrared radiation. Another significant patent is the Far Infrared Tandem Low Energy Optical Power Limiter Device. This device features multiple layers designed to protect thermal sensors against laser threats in the far infrared spectral region. The first embodiment includes an antireflective coating layer, a window substrate layer, a chalcogenide layer, a germanium substrate layer, and a vanadium dioxide layer. As incoming radiation energy increases, the vanadium dioxide layer transitions from a transmissive state to a reflective state, effectively managing excessive energy.
