Abstract:
A temperature detector comprising:a plate (2) of semiconductor material having a recess in which is disposed a sensitive element (3) which heats up in response to infrared radiation from a target; a thermally insulating layer (16) disposed between said sensitive element (3) and said plate (2); a thermo-electric element (6) which generates a first electric signal (V1) representative of the difference between the temperature of the target and a reference temperature; a device (5) for detecting temperature by contact, which emits a second signal (V2) representative of the reference temperature; and electronic processing means for providing an output signal representative of a temperature of the target, said processing means receiving the signals (V1, V2) emitted by the thermo-electric element (6) and the device (5) for detecting temperature by contact, said processing means being constituted by components formed in said plate (2) of semiconductor material.
