It is mainly about using the wave front interference principle of Moiré interferometry analyzed the possibility of non-contact measuring elastic modulus and Poisson ratio for high temperature materials by Moiré interferometry and the types of grating specimers of Moiré interferometry in high temperatures. The means of elastic modulus and Poisson ratio of the materials measured in high temperatures, and application for a large number of aviation materials are completed. A new perfect measuring way has been developed.
