基于事件的成像是一种神经形态检测技术，通过像素阵列检测每个像素处光强度的正或负变化，因此特别适合检测运动。与标准相机技术相比，基于事件的相机通过不检测图像中没有运动的区域来减少冗余，从而在不影响视场的情况下提高帧率。本研究将基于事件的成像技术应用于真空条件下悬浮微粒的运动检测，极大地促进了纳米热力学的研究，并使多粒子阵列的独立检测和控制成为可能。
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.
