以极高的时间分辨率记录图像的能力使各种应用成为可能，例如荧光寿命成像、飞行时间深度成像和超快过程的表征。最近，已经出现了超快成像方案，其需要长的采集时间或光栅扫描，并且需要足够的信号，这只能在光从物体反射或被强散射介质漫射时实现。在这里，我们提出了一个示范的潜在的单光子探测器阵列的可视化和快速表征的事件演变的皮秒时间尺度。单光子灵敏度、时间分辨率和全场成像能力使人们能够观察空气中的飞行光，以及测量自然环境中激光诱导等离子体的形成和动态。极高的灵敏度和较短的采集时间为超快过程的实时成像或隐藏在视野之外的物体的可视化和跟踪铺平了道路。 超快成像方案可以实现各种各样的应用，但需要长的采集时间或光栅扫描。在这里，Gariffin等人展示了使用单光子探测器阵列的飞行中的光和激光诱导等离子体形成的可视化和快速表征。
The ability to record images with extreme temporal resolution enables a diverse range of applications, such as fluorescence lifetime imaging, time-of-flight depth imaging and characterization of ultrafast processes. Recently, ultrafast imaging schemes have emerged, which require either long acquisition times or raster scanning and have a requirement for sufficient signal that can only be achieved when light is reflected off an object or diffused by a strongly scattering medium. Here we present a demonstration of the potential of single-photon detector arrays for visualization and rapid characterization of events evolving on picosecond time scales. The single-photon sensitivity, temporal resolution and full-field imaging capability enables the observation of light-in-flight in air, as well as the measurement of laser-induced plasma formation and dynamics in its natural environment. The extreme sensitivity and short acquisition times pave the way for real-time imaging of ultrafast processes or visualization and tracking of objects hidden from view. Ultrafast imaging schemes can enable a diverse range of applications but require long acquisition times or raster scanning. Here, Gariepy et al. demonstrate visualization and rapid characterization of light-in-flight and laser-induced plasma formation using single-photon detector arrays.
