Abstract
In order to orientate a non-orthogonal shafting laser theodolite measurement system quickly and accurately , a construction technology of variable-length photoelectric reference scale was proposed based on high-precision photoelectric position sensitive detector .Firstly, the feature of a non-orthogonal shafting laser theodolite was elaborated .According to the features and the orientation requirement of a non-orthogonal shafting laser theodolite measurement system , the general idea of the construction of variable-length photoelectric reference scale was confirmed .After that, the design of hardware circuit was finished and a variable-length photoelectric reference scale was constructed .Finally, spatial position relationship between two photoelectric position sensitive detectors was calibrated to realize the measurement of variable-length reference .The experiment results show that the relative measurement accuracy of variable-length photoelectric reference scale is better than 0.03%.The orientation of a non-orthogonal shafting laser theodolite measurement system can be realized conveniently and in high -precision.关键词
