About
Yeonsoo Ahn is a leading researcher in the field of CMOS image sensors, with a primary focus on indirect time-of-flight (iToF) depth-sensing technology. His most significant contribution is the development of a dynamic pseudo 4-tap iToF sensor that achieves motion artifact suppression and robust background light cancellation, even under extreme illumination conditions exceeding 120 klux. This work, published in 2020 and garnering 17 citations, addresses a critical challenge in 3D imaging: maintaining high spatial resolution and depth accuracy in real-world, high-dynamic-range environments. By advancing the design of scaled photodetectors and phase-measurement techniques, Ahn’s research enables more reliable depth perception for applications in autonomous systems, augmented reality, and industrial machine vision. His innovations directly improve the performance of iToF CMOS image sensors, which are essential for capturing both two-dimensional shape and precise depth information. Ahn’s work stands out for its practical impact, offering a path toward more robust, high-resolution 3D sensing that can operate reliably in challenging lighting conditions, a key requirement for next-generation smart devices and robotics.
