摘　　要：运用云纹干涉法的波前干涉原理和非接触测量面内位移方法,通过变形栅衍射的不同波前相干涉所产生的条纹来获取变形信息,对试件的弹性模量和泊松比进行测量,并将此方法应用于高温环境下航空高温合金材料的弹性模量和泊松比的测量.Our research is mainly about using the wave front interference principle of moiré interferometry and non- contact measuring the inside plane displacement to measure the elastic modulus and Poisson~ ratio of specimens. Transformative information can be obtained by the stripe generated by the different wave front interference originating from grating diffraction. In the high temperature circumstance, this kind of measuring can also be used to measure the elastic modulus and Poisson ＇s ratio of high - temperature aeronautical alloy materials.
