Abstract: Disclosed are a method and a system for acquiring three-domain information of ultrafast light field. The method includes: acquiring time-domain information at positions of respective spatial points in a first signal to be measured; acquiring first frequency-domain information of continuous light portions at positions of respective spatial points in a second signal to be measured; acquiring second frequency-domain information of pulse light portions at positions of respective spatial points in a third signal to be measured; and fusing the time-domain information, the first frequency-domain information, and the second frequency-domain information, and determining three-domain information of an ultrafast light field signal according to information obtained by the fusion; wherein, the first signal to be measured, the second signal to be measured and the third signal to be measured are three signals obtained by splitting the ultrafast light field signal to be measured.
