我们提出并实验证明了一种新的内窥镜概念：压缩多模（MM）光纤成像。我们表明，在MM纤维中产生的散斑图案代表了压缩感知的良好基础。我们展示了高分辨率压缩成像通过一个光纤探头的总测量次数比标准光栅扫描方法所需的内视显微镜少20倍。此外，我们证明了MM光纤的固有光学切片可以帮助克服压缩感知的主要问题，并可用于体结构的成像。压缩MM光纤成像不需要复杂的波前整形，显著提高了预校准和成像速度，创造了一种新的内镜显微镜方法。(C) 2018年美国光学学会
We propose and experimentally demonstrate a new concept of endo-microscopy: compressive multimode (MM) fiber imaging. We show that the speckle patterns generated in a MM fiber represent an excellent basis for compressive sensing. We demonstrate high-resolution compressive imaging through a fiber probe with the total number of measurements 20 times less than what is required for the standard raster scanning approach to endo-microscopy. Moreover, we show that the inherent optical sectioning of a MM fiber can help to overcome the main problem of compressive sensing and can be used for the imaging of bulk structures. Compressive MM fiber imaging does not require complex wavefront shaping and significantly increases the pre-calibration and imaging speed, creating a new approach to endo-microscopy.
