Based on the speckle pattern micro-displacement measurement technology and micro-displacement mode simulation methods, the measurement characteristics(the accuracy, the size of memory and the efficiency) of the various measurement algorithms, including Dirac, IDFT, MMSE1 and MMSE2, were analyzed and compared in the conditions of different noise environment, respectively. The experiment results will be benefit to the application in the engineering.
