摘　　要：激光位移传感器具有测量速度快、非接触等优势,广泛应用于许多测量与检测领域,为了提高激光位移传感器的测量精度,针对目前测量误差存在的不足,提出一种新型的激光位移传感器误差补偿方法。分析了激光位移传感器的测量原理,找出误差产生的原因,并推导出激光位移传感器的误差模型,然后采用对激光位移传感器测量误差进行修正和补偿,最用Matlab 2014工具箱进行仿真测试。结果表明,本文方法提高了激光位移传感器的测量精度,将激光位移传感器测量误差控制在实际应用的范围之内,具有较高的实际应用价值。Laser displacement sensor is widely used in many fields for its high measurement speed and non contact,in order to improve the measurement precision of the laser displacement sensor,a new laser displacement sensor error compensation method is proposed in this paper. We analyze the measuring principle of laser displacement sensor and analysis the causes of errors,and secondly the error model of laser displacement sensor is inferred,and combination model is used to correction and compensation measuring error the laser displacement sensor,at last,simulation testing is carried out on Matlab 2014. The results show that the proposed method can improve the measurement precision of the laser displacement sensor,and the measurement error is controlled within the range of practical application,and has high practical application value.
