| Abstract: | When the working range is very small,the displacement can be measured with a single multimode optical fibre sensor which has no blind zone.For this case,we have deduced the analytical expression for energy coupling efficiency.In addition,comparison between results predicted by this theory and those conventionally used has also been made. |

| Keywords: | optical fibre sensor energy coupling efficiency expression |
