The mode distributions at the end of a multi-modefiber and a channel waveguide were successfully imaged by the system.

The theoretical formulas of torsional Angle sensing are derived and the torsional Angle of this sensor is linear to the power loss of the multi-modefiber.
Based on mode field coupling theory, a model to calculate the butt-joint coupling efficiency between a multi-modefiber and a single-mode fiber is presented.
