An ultrafast compressive sensing imaging system is proposed using in-fiber grating. The in-fiber grating, namely 45° tilted fiber grating (TFG), acts as the in-fiber polarizer, and a lateral light diffraction device at the same time. Due to its polarization-sensitive feature, the 45° TFG along with the polarization modulator can perform the compressive sensing process. A state-of-art demonstration is performed based on the proposed imaging system and a field of view (FOV) of 2mm by 4mm and data compression ratios of 8% and 16% are achieved.
