基于DMD 的并行压缩感知时域关联成像

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 a-bility 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.
