Abstract

We present a method for acquiring a sequence of time-resolved images in a single shot, termed Single-Shot Non-Synchronous Array Photography (SNAP). In SNAP, a diffractive optical element is used to create an array of angled probe beams. Each of these sub-pulses then transmit through an echelon to impart unique time delays, creating an angled pulse train. After probing a scene, the sub-pulses can be differentiated with techniques from light field microscopy. Temporal resolution in SNAP is fundamentally limited only by the probe pulse duration. We demonstrate SNAP by capturing the evolution of a laser initiated plasma at an average framerate of 4.2 Tfps.
