The invention discloses a fiber Bragg grating two-dimensional vibration sensor with temperature compensation, which comprises an upper end cover, a T-shaped beam, a lower end cover and four fiber Bragg gratings, wherein the T-shaped beam comprises a cross beam and a vertical beam, the third fiber Bragg grating and the fourth fiber Bragg grating along the direction of the cross beam are connected through the first fiber Bragg grating arranged along the direction of the vertical beam, vibration acceleration parameters in the two mutually vertical directions can be measured in real time, temperature compensation is carried out on the first fiber Bragg grating through the second fiber Bragg grating, the T-shaped beam is adopted to act as an elastic body to realize vibration measurement, and the resonant frequency and the sensitivity of the sensor are effectively improved. Meanwhile, a pretightening force of the first fiber Bragg grating is changed through adjusting a pretightening screw, and the vibration measurement range along the direction of the vertical beam can be enlarged. According to the invention, the fiber Bragg grating two-dimensional vibration sensor transmits optical signals through optical fibers and has a higher anti-electromagnetic interference ability. In addition, multi-parameter distributed vibration dynamic measurement can be realized through connecting a plurality of the fiber Bragg grating two-dimensional vibration sensors with temperature compensation in series.
