摘 要: 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.
