Comparison work between the original data and compensated data was done and the results show that the proposed strategy could notablely reduce the non-linear error. 对修正前后的变化量进行了对比，结果显示该方法能显著的减小加工的非线性误差。
The nonlinearity error of the dual-frequency laser interferometer with two longitudinal modes and special subsequent electrical signal processing system was studied. 对具有特殊后续电信号处理系统的双纵模双频激光干涉仪的非线性误差进行了研究。
