About
Akihiro Odagawa is a leading innovator in advanced CMOS image sensor (CIS) technology, with a primary focus on long-range, high-resolution 3D time-of-flight (ToF) ranging systems. His most impactful work centers on the development of Geiger-mode avalanche photodiodes (Gm-APDs), also known as single-photon avalanche diodes (SPADs), integrated into CIS for direct ToF applications. His landmark 2020 paper, with 32 citations, details a 1200×900 resolution, 6µm-pitch sensor achieving 450fps. This system enables a remarkable 250-meter ranging capability by employing a novel "direct-indirect-mixed frame synthesis" technique, which allows for configurable depth resolution down to 10cm. This breakthrough directly addresses critical demands in automotive LiDAR, surveillance, and robotics for both long-distance detection and precise 3D imaging. Odagawa’s contributions are pivotal in pushing the boundaries of SPAD-based CIS, demonstrating that high-resolution, high-frame-rate, and long-range depth sensing can be achieved simultaneously, marking a significant advancement over conventional indirect ToF methods and establishing a new benchmark for solid-state 3D imaging systems.
