We demonstrate pixelation-free real-time widefield endoscopic imaging through an aperiodic multicore fiber (MCF) without any distal opto-mechanical elements or proximal scanners. Exploiting the memory effect in MCFs, the images in our system are directly obtained without any post-processing using a static wavefront correction obtained from a single calibration procedure. Our approach allows for video-rate 3D widefield imaging of incoherently illuminated objects with imaging speed not limited by the wavefront-shaping device refresh rate.
我们展示了通过无周期多芯光纤（MCF）实现无像素化的实时宽视野内窥镜成像，无需任何远端光机械元件或近端扫描仪。利用多芯光纤中的记忆效应，我们系统中的图像可直接获取，无需使用从单次校准程序获得的静态波前校正进行任何后处理。我们的方法允许对非相干照明物体进行视频速率的三维宽视野成像，成像速度不受波前整形设备刷新率的限制。
