摘要
分析研究了动态散斑相关条纹图的数字化、量化、空间相移误差及散斑随机噪声等因素对双脉冲激光数字散斑干涉系统位相重建精度的影响，并提出了控制测量误差的方法。
The performance of double pulsed digital speckle pattern interferometry based on a Nd∶YAG laser system and spatial phase shift algorithm is analyzed in detail, which involves the sampling error, digitization error, phase shift error and the error caused by random speckle noise. The computer simulations are also used to give an entire statistical estimation of errors and simulation results show good agreement with a theoretical analysis.
