我们首次展示了一种数字相位共轭技术，用于在多模光纤的末端产生一个尖锐的焦点。在105 μ m芯多模光纤的尖端，实验获得了对比度为1800的锐利焦点。对焦点的扫描也通过数字手段进行了演示。讨论了光照和光纤弯曲的影响。(C)2012美国光学学会
We demonstrate for the first time to our knowledge a digital phase conjugation technique for generating a sharp focus point at the end of a multimode optical fiber. A sharp focus with a contrast of 1800 is experimentally obtained at the tip of a 105 mu m core multimode fiber. Scanning of the focal point is also demonstrated by digital means. Effects from illumination and fiber bending are addressed. (C)2012 Optical Society of America
