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。 Optical encoder to replace the original mechanical spectrometer in the reading system to achieve a digital spectrometer reading system. The optical encoder center axis and the spectrometer’s central axis is fixed, the outer disk and the telescope bracket fixed to ensure that the optical encoder and telescope coaxial rotation, telescope rotation angle change value from photoelectric encoder to convert the electrical signal output and Through the digital display of the telescope rotation angle directly displayed figures, making the reading becomes very simple and quick, data repeatability, reliability, and accuracy has also been improved.
