A new scheme for strain and temperature measurement simultaneous is proposed using a single fiber Bragg grating(FBG).The FBG is divided into two sections which have an equal length,the epoxy glue is daubed on one section,and it is inserted in steel cannula.So the two sections can be regarded as two FBGs with different Bragg wavelengths.Using the differences of their Young′s moduli and coefficients of thermal expansion,both strain and temperature can be measured.in the measurement regions of 2 70...
