Event-Based Imaging of Levitated Microparticles

Check out our new ArXiv pre-print on detecting levitated microspheres using event based cameras.


Event-based imaging is a neurmorphic 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 detecting motion. As 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.
