论文摘要
基于事件的成像是一种神经型检测技术,在该技术中,一系列像素在每个像素处检测到光强度的正变化或负变化,因此特别适合检测运动。与标准摄像头技术相比,基于事件的摄像机通过不检测没有运动的图像区域来降低冗余,从而允许增加帧速率而不会在视野上损害视野。在这里,我们采用基于事件的成像来检测真空条件下悬浮的微粒的运动,这极大地促进了纳米热力学的研究,并实现了许多颗粒阵列的独立检测和控制。
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.
