通过金色螺旋多芯光纤的非线性成像
Nonlinear imaging through a golden spiral multicore fiber
摘要：
我们报告了一种新型的金色螺旋多芯光纤的双光子无透镜成像。这种独特的布局优化了旁瓣电平、视场、串扰、群延迟和模式密度，实现了至少10.9 dB的旁瓣对比度。我们通过实验证明了用飞秒脉冲产生和扫描焦点并进行双光子成像的能力。
英文摘要：
We report two-photon lensless imaging through a novel golden spiral multicore fiber. This unique layout optimizes the sidelobe levels, field of view, cross-talk, group delay and mode density to achieve a sidelobe contrast of atleast 10.9 dB. We demonstrate experimentally the ability to generate and scan a focal point with a femtosecond pulse and perform two-photon imaging.
