摘要
A method and system for real-time measurement of ultrafast time/space/frequency domain information based on time/space/frequency compression. The method comprises: generating an ultrafast pulsed optical signal in a physical system to be observed; performing strength modulation spatial coding processing on the ultrafast pulsed optical signal; arranging, in the spatial horizontal direction by means of a time-space editor, a time domain sequence of the coded ultrafast pulsed optical signal obtained by the processing; performing, by means of the frequency-space editor, frequency light splitting processing on the time-space distribution coding form of the coded ultrafast pulsed optical signal obtained by the arrangement; performing, by means of a frequency-time delay device, frequency-time delay on the coded time/space/frequency synchronous ultrafast pulsed optical signal obtained by the processing; inputting to a flat panel detector the high-frequency resolution coded time/space/frequency synchronous ultrafast pulsed light signal obtained by the delay; performing real-time compression and collection to obtain compressed coded data information; and performing data decompression and decoding according to the compressed coded data information to obtain time/space/frequency domain synchronization information of the ultrafast pulsed optical signal. The present method can achieve real-time measurement of ultrafast time/space/frequency domain information.
