About
Sang-Man Han is a leading figure in the field of CMOS image sensor design, with a particular focus on Time-of-Flight (ToF) range imaging technology. His research centers on developing high-performance, sub-centimeter resolution 3D imaging systems for applications ranging from gesture-based controllers and robotics to automotive safety and security. Han’s most notable contribution is his pioneering work on a 413×240-pixel ToF CMOS image sensor that achieves sub-centimeter depth resolution. This sensor, detailed in his highly cited 2014 paper (20 citations), introduces an innovative in-pixel background canceling technique using lateral-electric-field charge modulators. This design breakthrough effectively suppresses ambient light interference, a critical challenge in outdoor or brightly lit environments, enabling more robust and accurate depth sensing. By integrating the background canceling directly into each pixel, Han’s architecture significantly improves signal-to-noise ratio without sacrificing pixel density or speed. His work represents a key advancement in solid-state 3D imaging, bridging the gap between high-resolution depth mapping and practical, real-world operating conditions.
