电荷耦合器件光学多道分析系统

An Optical Multichannel Analyzer with Charge-coupled Devices

将一台平面光栅单色仪改装成多色仪，利用线阵电荷耦合器件作其接收元件，并通过计算机进行实时数据采集和图像处理．采用该系统以铁谱作基准，对Ｈα展开模拟测量．结果表明：整个系统的测量误差接近０．１ｎｍ。

polychromator has been developed by way of refitting a plane grating monochromator with a charge-coupled device(CCD) array receiver.Both the data acquisition and the image processing can be completed leaf time with a computer system. The Hα spectra were measured and calibrated against the iron spectra. The results show that systematic errors are close to 0.1nm.
