Using wave guide theory, we deduce scalar approximate solution about transmissive light through a fiber weak-guide and give the expressions of field in each component.
根据光波导理论，推算出弱导条件下光沿光纤传输场的标量近似解，给出场的各分量表达式，以便分析讨论。

The apparatus that combined lightfiber and image fiber could provide visible image of inside bodies and could guide laser exactly to focus.
此装置结合了传像光纤和传光光纤，具有可视性，可将激光准确导入病灶。

The other is photonic band-gap fiber, which guide-light mechanism is very different with the traditional fiber.
