| 释义 |
Ultrafast imaging is concerned with the imaging of dynamic processes using frame rates of 0.1 GHz or faster.[1]. Since conventional high-speed cameras such as high-speed CCD or CMOS cameras are generally limited by electronic readout times, direct GHz or faster imaging is not generally practical for these devices. In order to bypass the electronic limitations, several optical techniques have been created for ultrafast imaging, most of which generally encode image information optically prior to capture by the camera and utilize computational techniques to recover the individual frames. The development of ultrafast imaging techniques is very important in scientific laser applications, particularly for studying processes that have significant shot-to-shot behavior (e.g. laser-induced plasma generation) and are stochastic in nature [1] Since the exposure times for ultrafast imaging are necessarily very short, a major challenge with ultrafast imaging is collecting enough photons from the target to have a quality signal. For this reason, ultrafast imaging is typically combined with pulsed laser sources for illumination. This is especially true given the development of ultrafast laser systems. Demonstrated Ultrafast Imaging TechniquesA partial list of ultrafast imaging techniques is as follows:[1]
