摘　　要：以研究实用性强、细分精度高的莫尔条纹信号细分方法为目的,提出乘法倍频技术与锁相式莫尔条纹信号细分方法相结合的新方案,并通过理论分析与实验仿真,验证了该方案的可行性与实用性.结果表明,所提出的新方案可改善原始信号的质量,降低对光栅传感器输出信号正交性、等幅性等方面的要求,并能提高细分精度,具有重要的实际应用价值.In order to research the practicability and subdivision precision of the Moiré fringe signal, a new method was proposed in which frequency multiplication technology is combined with the phase-locking Moiré fringe subdivision method. The theoretical analysis and experimental simulation prove that the method is feasible and practical. The results show that the method can improve the quality of the original signal, reduce the demand of the orthogonality and equiamplitude, and improve the subdivision precision, and has important application value.
