We construct an experimental measurement system for rotation vibration signal detection using the orbital angular momentum (OAM) of light in a Sagnac interferometer. Inputting light beams with different OAM, we demonstrate that the measured signal and signal-to-noise ratio can be increased by the OAM mode index l. In addition, the Sagnac interferometer can further improve the vibration signal and suppress the environmental noises. Such system has potential applications in high-precision sensing and monitoring of rotation vibrations.
