    • There is described a method and apparatus for providing temperature compensation for a variation of output of an electronic component as the temperature of the component fluctuates. The method and apparatus is particularly applicable to the voltage output of a photodiode when operated at different temperatures, to provide a consistent voltage output for a predetermined light level incident on the photodiode. The method and apparatus is also usable in conjunction with other electronic components exhibiting performance variations with temperature. In a particularly advantageous embodiment, the temperature compensation method and apparatus is used in an X-ray inspection device wherein X-rays passing through a product under inspection are incident on a flourescent element which emits light onto a number of photodiodes.
    • 描述了一种用于当部件的温度波动时为电子部件的输出的变化提供温度补偿的方法和装置。 所述方法和装置特别适用于在不同温度下操作时光电二极管的电压输出,以便为入射在光电二极管上的预定光级提供一致的电压输出。 该方法和装置也可以与显示出随温度的性能变化的其它电子元件一起使用。 在特别有利的实施例中,温度补偿方法和装置用于X射线检查装置,其中通过检查中的产品的X射线入射到在多个光电二极管上发光的荧光元件。
