About

S. Bellisai is a specialist in advanced 3D imaging systems, with a core focus on developing high-speed, low-power depth-sensing technologies using Single Photon Avalanche Diode (SPAD) arrays. Their major contribution lies in pioneering the application of continuous-wave indirect time-of-flight (ToF) methods for real-time three-dimensional ranging. In their seminal 2010 work, "3D ranging with a high speed imaging array," Bellisai demonstrated a novel system that leveraged a general-purpose CMOS SPAD sensor to capture 3D scans by reading the phase shift of modulated light, achieving high frame rates. This foundational paper, cited 9 times, established a new approach for compact depth sensing. Bellisai further advanced the field in 2012 with "Low-power 20-meter 3D ranging SPAD camera," which achieved a 20-meter range while maintaining low power consumption—a critical breakthrough for applications in automotive active safety, industrial robotics, and cultural heritage preservation. This work, with 4 citations, underscored the potential for SPAD-based cameras to replace bulkier, more power-hungry systems. Bellisai’s research is notable for bridging the gap between high-performance laboratory prototypes and practical, deployable sensors, making them a key figure in the evolution of efficient 3D vision technology.
