As the intensity of light varies - by the breaking of a light beam, say, or a decrease in general illumination - the amount of current generated by the sensor changes.
光线强度的变化(如光束被遮断或是一般照明的降低)会造成侦测器里产生的电流随著改变。

Target detection of the passive bistatic radar by non-cooperative illumination is a focus on which the current ECM study is made of for its advantages of "four countermeasures" .
利用外照射源对目标进行探测是目前电子对抗研究的一个热点，因为该体制雷达具有良好的“四抗”性能。

Current status of design in intelligent illumination control system was described, and the disadvantages of low intelligence, ossified manipulation and low efficiency of energy saving were brought up.
