About

Jaehyuk Choi is a leading innovator in the field of advanced CMOS image sensors and LiDAR technology, with a primary focus on time-of-flight (ToF) depth sensing for autonomous systems and augmented reality. His major contributions center on overcoming critical challenges in ToF sensors, including motion artifacts and high-background-light interference. In his highly cited 2020 work, Choi introduced a dynamic pseudo 4-tap CMOS time-of-flight image sensor that achieves robust motion artifact suppression and background light cancellation even under extreme conditions exceeding 120 klux, a breakthrough that significantly enhances sensor reliability in outdoor environments. More recently, his 2025 research on asynchronous flash LiDAR sensors demonstrates a novel pixelwise ToF validation method using a background-light-adaptive threshold, enabling dynamic frame rates from 5 to 250 fps—a key advancement for real-time 3D mapping in autonomous vehicles and robotics. With over 18 citations on these foundational papers alone, Choi’s work is shaping the next generation of high-performance, robust depth-sensing systems, establishing him as a pivotal figure in the evolution of solid-state LiDAR and indirect ToF imaging.
