Title:
METHOD AND SYSTEM FOR ACQUIRING THREE-DOMAIN INFORMATION OF ULTRAFAST LIGHT FIELD
Document Type and Number:
WIPO Patent Application WO/2020/232788
Kind Code:
A1
Abstract:
The present application relates to a method and system for acquiring three-domain information of an ultrafast light field. The method comprises: acquiring time-domain information of each spatial point position in a first signal to be measured; acquiring first frequency-domain information of a continuous light portion at each spatial point position in a second signal to be measured; acquiring second frequency-domain information of a pulsed light portion at each spatial point position 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 through 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 means of splitting the ultrafast light field signal to be measured. By means of the method and system for acquiring three-domain information of an ultrafast light field provided in the present invention, real-time measurement of three-domain information, i.e. time-domain information, spatial information and frequency-domain information, of an ultrafast light field signal can be realized, and the present invention has relatively high integrity and timeliness.
