摘要
本文研究了热电型非制冷焦平面红外探测器在 4状态斩波调制下的信号响应 ,从理论上得到了响应信号的变化 ,数值模拟分析表明 ,响应信号的变化可以反映出景物入射辐射在双波段的差异 ,由此可望通过单一非制冷钛酸锶钡 (BaxSr1-xTiO3 ,BST)焦平面探测器 。
The signal responses under 4 states of chopper modulation in the pyroelectric uncooled focal plane array (FPA) infrared detector are investigated and their changes are worked out theoretically.The digital analog analyses of their values show that the difference in the signal response reflects the variation in dual bands for the incident emission of the scene.Hence,it is expected that by using a single uncooled Ba xSr 1-x TiO 3(BST) FPA detector,a thermal image system (TIS) may be realized for acquisition of scenic dual bands information.
