摘要
为适应野外测量、应急检测以及在线监测的需要,开发了便携式快速光谱分析仪。该仪器采用线阵CCD作为检测器,可进行多光谱同时测量;采用触摸屏作为人机交互接口,可进行图谱显示和触控操作;采用电池组供电,增加了仪器使用的灵活性。文中对该仪器的分光系统作了介绍,并着重说明了光谱分析仪中CCD的时序控制方法以及其他一些注意事项。基于CCD的便携式光谱分析仪是紫外可见分光光度计的发展方向,该仪器可以实现快速光谱扫描、光度测量、时间扫描等功能,具有体积小巧、检测速度快、操作简便等优点。
To meet the application of measurement in the field,emergency detection and monitoring of online,the portable rapid-measure spectrometer is developed.In the spectrometer,the linear CCD-array is used as detector,so multispectral images can be measured at the same time;Touching screen is used for spectrum diagram display and touch-control operation;Using battery power,increase the flexibility of the instrument.In this paper,spectroscopy system is introduced.Especially,it is mostly introduced the controlling approach of CCD and some notes of the application of CCD.Portable spectrum analyzer based on CCD is the development direction of UV-Vis spectrophotometer.The spectrophotometer can achieve rapid spectral scanning,photometric measurement,time scanning and other functions,which has many advantages,such as compact size,fast detection speed,easy operation and convenience.
