Abstract
The effect of strain upon both the fluorescence intensity ratio and the fluorescence decay-time–temperature-sensing techniques has been studied using Yb-doped fiber. The measured variation with strain of the former method is consistent with no strain sensitivity, while the latter method demonstrates a linear dependence on strain. A single optical sensor element using both these fluorescence techniques thereby offers an attractive way of providing temperature compensation in a simultaneous strain and temperature monitoring system.Keywords
