| 中文摘要 | a specklegram in a multimode fiber (mmf) has successfully been used as a sensor for detecting external disturbance. our experiments showed that the sensitivity in the sensor with a multiple longitudinal-mode laser as its source was much higher than that with a single longitudinal-mode laser. in addition, the near-field pattern observations indicated that the coupling between different transverse modes in the mmf is quite weak. based on the experimental results, a theoretical model for the speckle formation is proposed, taking a bend-caused phase factor into consideration. it is shown in the theoretical analysis that the interferences between different longitudinal modes make a larger contribution to the specklegram signals.
