Description
Summary:Serial time-encoded amplified microscopy can achieve ultrafast imaging speed within varied dynamic regimes. However, it has two challenges: the high-throughput data issue and low-efficiency diffraction issue. Here, we report a compact and highly efficient ultrafast optical imaging system based on compressive sensing and in-fiber grating. Our proposal is confirmed by the proof-of-principle experiment and obtains a minimum data compression ratio of 5% with a continuous ultrafast imaging speed of 10 Mfps at a field of view of 0.5 mm*1.6 mm. A barcode with a moving speed of 4m/s is also demonstrated for imaging and an imaging speed of 1.25 Mfps is obtained. The proposed optical imaging system overcomes the big data issue, increases energy efficiency, and paves the way for compact and highly efficient ultrafast optical imaging within dynamic scenarios.
