We are pleased to announce the publication of the book "Design of event-driven spad-based 3D image sensors" in which our Institute's researchers, Juan Antonio Leñero Bardallo and Ángel Rodríguez-Vázquez, appear as co-authors
The book presents a top-down circuit description for implementing asynchronous vision sensors based on single-photon avalanche diodes (SPADs). It offers design considerations for transmitting SPAD pulses through a channel shared by all pixels. It also presents architectures where dynamic vision sensors and SPADs converge.
The book "Design of Event-Driven Spad-Based 3D Image Sensors" offers detailed technical information on new image sensor architectures with SPADs and asynchronous operation. At the sensor level, the book provides asynchronous circuitry for reading and arbitrating pixel outputs. The authors explore new LiDAR architectures with asynchronous operation and offer insights into their design. A detailed comparative analysis of modern, competitive LiDAR systems is also presented. At the pixel level, the book provides design considerations for transmitting SPAD pulses over a channel shared by all pixels. At the sensor level, the book provides asynchronous circuitry for reading and arbitrating pixel outputs. Finally, experimental results of very novel LiDAR systems with asynchronous operation will be presented and analyzed.
The book is written for professionals who want to explore new trends in image sensor design for LiDAR system implementation.
