Abstract
By monitoring temporal contrast, event-based vision sensors can provide high
temporal resolution and low latency while maintaining low power consumption and
simplicity in circuit structure. These characteristics have garnered
significant attention in both academia and industry. In recent years, the
application of back-illuminated (BSI) technology, wafer stacking techniques,
and industrial interfaces has brought new opportunities for enhancing the
performance of event-based vision sensors. This is evident in the substantial
advancements made in reducing noise, improving resolution, and increasing
readout rates. Additionally, the integration of these technologies has enhanced
the compatibility of event-based vision sensors with current and edge vision
systems, providing greater possibilities for their practical applications. This
paper will review the progression from neuromorphic engineering to
state-of-the-art event-based vision sensor technologies, including their
development trends, operating principles, and key features. Moreover, we will
delve into the sensitivity of event-based vision sensors and the opportunities
and challenges they face in the realm of infrared imaging, providing references
for future research and applications.
