Abstract
The present application relates to a real-time measurement method and system for ultrafast space-time-frequency three-domain information based on space-time-frequency compression. The method includes: generating an ultrafast-pulse optical signal in a to-be-observed physical system; performing intensity-modulated spatial encoding on the ultrafast-pulse optical signal; arranging, by a space-time editor, a time-domain series of an encoded ultrafast-pulse optical signal in a horizontal space direction; performing, by a frequency-space editor, frequency spectral processing on a space-time distribution encoding form of the encoded ultrafast-pulse optical signal; performing, by a frequency-time delayer, frequency-time delaying on an encoded space-time-frequency synchronized ultrafast-pulse optical signal; performing, by an area array detector, real-time compression and acquisition on a high-frequency-resolution encoded space-time-frequency synchronized ultrafast-pulse optical signal, to obtain compressed encoded data information; and decompressing and decoding data according to the compressed encoded data information, to obtain space-time-frequency three-domain synchronization information…
