Abstract
Event-based imaging is a neuromorphic detection technique whereby an array of pixels detects a positive or negative change in light intensity at each pixel and is, hence, particularly well suited to detect motion. Compared to standard camera technology, an event-based camera reduces redundancy by not detecting regions of the image where there is no motion, allowing increased frame-rates without compromising on field-of-view. Here, we apply event-based imaging to detect the motion of a microparticle levitated under vacuum conditions, which greatly facilitates the study of nanothermodynamics and enables the independent detection and control of arrays of many particles.
