The Study and Design of Anti-light Interference in PDT
This paper aims at the question about the gunpoint light affection when the photoelectric detection target (PDT) works before the gunpoint. The long rectangular photo detector that have high response and low noise performance is used to expand the field of detecting view and improve the detecting performance. The feature that the light of gunpoint and the signal of projectile are work at the same time in the whole array photo detector was used to analyze and design anti-light interference circuit. Under the condition that the detecting visual field of PDT meet the request, the array photo detector was divided into three parts to distinguish the signal of gunpoint light and flying projectile, analyzed the relation between gunpoint light and the projectile information, the reasonable the detecting circuit in the PDT is designed. It makes the influence of gunpoint light is minimum, and the signal of flying projectile is distinct; the measure is very availability to eliminate the interference of gunpoint light.
