| Abstract: | 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's 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. |

| Keywords: | high-temperature moiré elastic modulus Poisson's ratio |
