摘要
设计并制作了一种用于子午工程探空火箭上的大气微量成分探测仪。选择了合适的硅光电池作为光电探测器件,并通过合理的光谱剪裁保留了250～420nm波段的光,设计了微电流放大电路以及信号采集系统,实时地对臭氧以及二氧化氮的含量进行监测。实际的测量结果表明:仪器对低纬地区大气微量成分的测量是准确可靠的。
A rocket-borne detector for atmosperic element measurements is designed and fabricated. A appropriate silicon photoelectric cell is selected as photoelectric detector and light in 250 -420 nm is reserved through optimum spectrum clipping. Microcurrent amplifier and signal collecting system are designed to detect the atmosper- ic element in good time. The application results show that the measurements of this equipment are trust and reliable.
