A digital laser holographic interferometric device was designed to measure the Poisson ratio of composite materials based on the digital holography principle .Using this device ,the Poisson ratio was obtained through sample loading ,holograph recording and numerical holograph reconstruc-tion and calculation ,and the non-contact and real-time measurement were realized .The results in C/C composite material indicated that the experiment was accurate and the repeatability was good .
