用全息法测量了几种材料的泊桑比。说明了全息法对测量小泊桑比和脆性材料的泊桑比有独特的优越性。通过理论验证,测量结果准确,精度达千分位。
Poisson’s ratio of several materials was measured by holography. The holographic method has unique advantages for measuring Poisson’s ratio of small Poisson’s ratio and brittle materials. Through theoretical verification, the measurement results are accurate and the accuracy reaches the thousandths place.
