PROBLEM TO BE SOLVED: To provide a measuring device and a measuring technique of a rotor capable of measuring physical quantities of a rotor preferably. SOLUTION: The measuring device of a rotor includes a rotating section 2 with a measured rotor, a fixed supporting section 3 supporting the rotating section 2 rotatably, an optical fiber 5 a FBG sensor section 4 is formed as a measuring means of the rotor, a rotary joint 6 connecting the optical fiber 5 between the rotating section 2 and the fixed supporting section 3 so as to elongate the optical fiber 5 from the rotor to the fixed supporting section 3, a luminous source 7 emitting light to the optical fiber 5 continuously, an optical circulator 8 separating reflected light from the FBG sensor section 4, and a signal processing section 12 computing physical quantities of the rotor by processing the signal of reflected light.
