摘要
研发了1种可应用于环境监测的微尺度光电检测系统。该系统基于物质吸光理论，以发光二极管（LED）为光发射器件，以光电池为光接收器件．配以适当的检测电路，实现了对溶液锌离子浓度的检测。整个系统具有携带方便、光学元件少、测量精度较高、结构简单紧凑、体积小、成本低廉等优点。通过结构与参量优化设计的初步实验结果表明，微型光电检测系统可以实现溶液浓度的较精确测量，也可用于气体环境因素的检测。
A micro-photoelectric detection system applicable to the environmental monitoring has been developed. The detection system is based on the theory of photoabsorption by substances. The developed system is composed of a light-emitting diode （LED） as light emission component, a photocell as light receptor and associated circuits. The whole system is light, cheap and portable with many advantages such as fewer optical elements, higher accuracy, simple in structure, small in size, and etc. The preliminary experimental results showed that the mini-sized photoelectric detection system could do the determination of zinc ion concentration in aqueous solutions, and could also be applied to detecting factors in gaseous environment as well.
