A compressive sensing single pixel imaging system using in-fiber grating

We present a compact and high-efficient compressive sensing based single pixel imaging system employing an in-fiber grating. The in-fiber grating, which is called 45° tilted fiber grating (TFG), is utilized as the in-line polarizer, a lateral diffraction device and a light emitter at the same time. Our demonstration results shows data compression ratios from 5% to 20% are achieved in the presented system.
