Unlikely other papers, which use optical filters, the Multi-FGB sensor system, which measures the variation of the wavelength through the spectral slope of the SLD optical source and multiplexed using code-division multiplxing is proposed. The Multi-FGB sensor system, can be realized in cheap price and reduced components. Also, using electrical strain gauge the linearity of FBG sensor system is conformed and the dynamic strain can be measured as well.
