水准仪数字化改造中光电成像系统的设计

Design of the Optics-electricity Imaging System on Digital Levels Research

以光学自动安平水准仪为依托,对水准测量的数字化进行研究,在光学自动安平水准仪的主光路中增设偏振分光镜,选取线阵CCD图像传感器作为标尺图像采集器件,确定了各部分的参数,完成光电成像系统的设计。实验测试表明,设计的样机整体性能较好,可以满足电子读数的要求。

Based on automatic level, research is conducted on the digital measurement of levels. Meanwhile, increased polarizing beam splitters are set up in the main light road of the automatic determining the parameter of each part. Thus the design of the optics-electricity imaging system of digital level is finished. The sample digital level is found to function well after experiments and tests. It can read the numbers electronically.
