    • 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.
    • 公开了一种用于感测来自物体的红外辐射的红外传感器组件。 红外传感器组件包括传感器阵列,该传感器阵列包括设置在基板平面上延伸的基板上或嵌入到基板中的多个感测元件。 传感器阵列包括至少两个红外感测元件,每个红外感测元件具有响应于入射到其上的红外辐射的比例电信号和至少两个盲感测元件的辐射响应元件,至少一个盲感测元件散布在 至少两个感测元件,每个盲感测元件被屏蔽不受来自物体的入射红外辐射,并响应于寄生热通量提供成比例的电信号。 传感器阵列的输出是红外感测元件和盲目感测元件的函数,使得寄生热通量至少部分被补偿。
