Abstract

For the problem of large computation and slow speed to generate the focused spots in the multimode fiber digital scanning imaging method, the digital scanning imaging method with a single multi-mode fiber (MMF) was proposed based on adaptive parallel coordinate(APC) algorithm. By controlling the input field of the MMF, the focused spots were formed. The theoretical imaging model of single MMF digital scanning was established. APC algorithm was adopted to optimize the phase on the spatial light modulator (SLM), which can effectively reduce the time to form focused spots and improve the imaging speed. 30 ×30 focused spots were formed to sample the resolution target in 50 μm ×50 μm region. The experiment demonstrates that the object on the sample plane 60 μm far from the MMF output end can be reconstructed. The resolution is 2.46 μm.
