摘　　要：采用半导体激光器、CCD显示单元和高精度实心轴角度传感器对传统分光计进行改进,实现了分光计的激光自准直调节,使得分光计的粗调能有的放矢,减少了盲目调节;望远镜图像液晶显示缓解了实验者的视觉疲劳,减少了视差;读数系统的数字化,使得读数变得非常简单快捷,数据的重复性和可靠性更好.By using the semiconductor laser,the CCD display unit and a high precision solid axis angle sensor to improve the traditional spectrometer,the adjustment of spectrometer laser self-collimation can be achieved,which makes the coarse adjustment of spectrometer purposefully and reduces the blind adjustment.The liquid crystal display of telescope images alleviates the experimenter's visual fatigue and reduces the parallax.The digital reading system makes not only readings become very simple and fast,but also the repeatability and reliability of data become better.
