Analysis for measurement precision of Projection Speckle Correlation Method (PSCM)
投影散斑相关法测量精度影响因素的综合分析

This paper has examined measuring displacement precision of the PSCM with the experimental method.The record angle,projection angle and defocus are analyzed to the results of the measurement. The experimental results show that PSCM is a high measuring precision system of displacement and that it is a better measuring method of applying in engineering tests.
