| Abstract: | Simultaneous measurement for strain and temperature is the key and difficult point. This paper firstly introduces the physical mechanism of producing cross sensitivity, then presents the solution viewing from the dual wavelength matrix method, and the double-parameter matrix method and temperature (strain)compensation method, while analyzing the methods, so that we can choose an optimal solution according to application. |
