    摘要: An infrared sensor assembly for sensing infrared radiation comprises infrared sensing elements and the infrared sensing compensation elements that are different so that, for a same flux on the infrared sensing elements and the infrared sensing compensation elements, the radiation responsive element of the infrared sensing elements absorbs more radiation than the radiation responsive element of the infrared sensing compensation elements, as to receive substantially more radiation than the radiation responsive element of the infrared sensing compensation elements. An output of the sensor array is a subtractive function of a sum of the signals of the plurality of infrared sensing elements and a sum of the signals of the plurality of the infrared sensing compensation elements such that at least linear and/or non-linear parasitic thermal fluxes are at least partly compensated for.

    摘要: An infrared sensor assembly for sensing infrared radiation from an object is disclosed. The infrared sensor assembly comprises a sensor array comprising a plurality of sensing elements, provided on or embedded in a substrate extending in a substrate plane. The sensor array comprises at least two infrared sensing elements, each infrared sensing element having a radiation responsive element providing a proportionate electrical signal in response to infrared radiation incident thereto and at least two blind sensing elements, at least one blind sensing element being interspersed among the at least two sensing elements, each blind sensing element being shielded from incident infrared radiation from the object and providing a proportionate electrical signal in response to parasitic thermal fluxes. The output of the sensor array is a function of the infrared sensing elements and of the blind sensing elements such that parasitic thermal fluxes are at least partly compensated for.

    摘要: A semiconductor device for measuring IR radiation comprising: at least one sensor pixel; at least one reference pixel shielded from said IR radiation comprising a heater; a controller adapted for: measuring a responsivity by applying power to the heater, while not heating the sensor pixel; measuring a first output signal of an unheated pixel and a first reference output signal of the heated pixel, obtaining the responsivity as a function of a measure of the applied power to the heater and of the difference between the first output signal and the first reference output signal; applying a period of cooling down until the temperature of the reference pixel and the sensor pixel are substantially the same; generating the output signal indicative of the IR radiation, based on the difference between the sensor and the reference output signal, by converting this difference using the responsivity.
