PROBLEM TO BE SOLVED: To provide a physical quantity measurement system and a physical quantity measurement method capable of measuring simultaneously each physical quantity on a plurality of spots.SOLUTION: An FBG line formed by connecting a plurality of FBGs in the columnar state is connected to the first to the N-th input-output ports of a light switch 13, and a measuring beam inputted from a common port is outputted from each input-output port of the light switch 13 at each different timing, and reflected light reflected by some FBGs of the FBG line 30 is separated in each wavelength by an AWG 15 and received by PDs 16. |
