| 摘要 |
An infrared sensor (400) comprises a first sensing element (410), comprising a set of N thermocouples (412) on the substrate whose hot junctions may receive radiation from a source external to the sensor; a second sensing element (420) comprising a set of N thermocouples (422) on the substrate whose hot junctions may not receive radiation from a source external to the sensor; first and second connection modules (307, 306) for connecting a number N1, N2 of thermocouples of the first or second sensing element (410), respectively; and connecting means for connecting an output of the first connection module (307) of the first sensing element (410) with an output of the second connection module (306) of the second sensing element (420), and an output (407, 408) for outputting the combined outputs of the sensing elements as a measure of the temperature. |
