About

Philip Choi is a leading figure in the development of advanced observational techniques for small-aperture telescopes, with a particular focus on near-Earth object (NEO) detection and high-resolution imaging. His most cited work introduces synthetic tracking (ST), a powerful method that overcomes the traditional "trailing loss" problem when observing fast-moving NEOs. By enabling prolonged integration times on modest telescopes, ST dramatically boosts detection sensitivity and astrometric accuracy—a breakthrough that democratizes NEO surveys by allowing small observatories to contribute meaningfully to planetary defense. This 2024 paper has already garnered 13 citations, signaling its rapid impact. Earlier, Choi pioneered the CAMERA system (2008, 4 citations), a compact, automated laser guide star adaptive optics platform. Designed for permanent installation on small telescopes, CAMERA delivers diffraction-limited visible and near-infrared imagery, unlocking high-angular-resolution science without the need for large, oversubscribed facilities. Together, these contributions establish Choi as a key innovator in making cutting-edge observational capabilities accessible to the broader astronomical community, with direct implications for asteroid hazard assessment and high-resolution stellar imaging.
