A measurement method that combines parallel compressed sensing and temporal ghost imaging for the high-speed detection of non-periodic time-varying light signals is proposed.With the help of the high-speed modulation ability of the spatial light modulator DMD,the fast time-varying signal can be recovered within a single exposure time of the detector,with good recovery effect for non-periodic fast time-varying signals.Through experimental verification,this method can recover time-varying signals with a frequency of 1kHz and has a high signal-to-noise ratio.
