双色探测作为一种增加不同环境下探测几率的方法已变得越来越合乎需要。双色光电探测器可以用来区分两个不同的目标。当两个温度不同的目标以不同的波长发射红外辐射时,双色光电探测器就能比较容易地将它们区分开来。例如,当两辆同样的小汽车紧挨着停在一起时,如果其中一辆刚刚被驾驶过,而另一辆最近几个小时内没有被驾驶过,那么双色探测器就能容易地探测到它们的排气管或轮胎的温差。在军事上,双色光电探测器则可以用来探测经过伪装的目标。
Two-color detection as a way to increase the probability of detection in different environments has become more desirable. Two-color photodetectors can be used to distinguish between two different targets. When two different temperature targets emit infrared radiation at different wavelengths, the two-color photodetector can more easily distinguish them. For example, when two identical cars are parked next to each other, the two-color detector can easily detect if one has just been driven and the other has not been driven in the last few hours The temperature difference between their exhaust pipes or tires. Militarily, two-color photodetectors can be used to detect disguised targets.
