【摘要】提出利用光纤基线代替野外基线标定激光测距仪的方法,将室外基线引入到室内.研究激光到光纤耦合方法并选取适当的耦合元件参数,搭建稳定的激光器到光纤高效耦合平台.对3段不同长度光纤基线进行了光程长度测量实验,分析了光波长、温度、聚焦透镜、色散等因素对测量结果的影响.实验获得了稳定的测量数据,测量结果偏差在2 mm以内,验证了方法的可行性.%A novel scheme of calibrating the laser rangefinder using optical fiber baseline is proposed. Coupling between laser beam and optical fiber is studied for the optical components design. By establishing the coupling system between laser diode and optical fiber, the outdoor baseline is successfully replaced by the indoor optical fiber. Optical path length measurement experiments are conducted on three kinds of fibers. Effects of wavelength, temperature and material dispersion on the experiment results are discussed. Stable data are derived in the experiments, the deviation is proved to be within 2 mm, indicating that the proposed calibration method is feasible. 【总页数】5页(830-834)
