| 摘 要： | 采用光电编码器取代分光计中原来的机械读数系统,实现了分光计读数系统的数字化。将光电编码器的中心轴与分光计的中心轴固定,外盘与望远镜的支架固定,保证了光电编码器与望远镜同轴转动,望远镜转动的角度变化值由光电编码器转换成电信号输出,并通过数字显示器将望远镜转动的角度值直接用数字显示出来,使得读数变得非常简单快捷,数据的重复性、可靠性更好,同时精度也得到了提高。

| Abstract: | It is rather complex,time-consuming and easily mistakable when using the traditional spectrometer to measure the rotate angle by relying on the mechanical dial reading system to get the angle value.What is more,4 sets of data are needed to get the final angle value via calculating.Using precise photoelectric encoder to replace the original mechanical reading dial of the spectrometer,the spectrometer is digitized.Fix the central axis of the photoelectric encoder with the axis of the spectrometer,the synchron... |
