In order to accomplish the all-optical control in the aspect of tempaerature sensors, a theoretical design of temperature sensors is proposed based on the nonlocal spatial solitons. Taking lead glass as the propagation media of the soliton, the phase shift of the center-incident soliton is studied in the cylindrical lead glass. It is concluded that a temperature change of 0.32 ℃ can lead to π phase shift of the nonlocal solitons. The phase shift modulation by the temperature change will be a practicable and sensitive design of the temperature sensor based on the interferometer theory.
