High temperature components are widely applied in aviation,power plant,petroleum and chemical industries.In these fields,displacement,deformation and strain measurement has been widely used to identify the presence,location,and severity of damage in components,owing to its sensitive characteristic to local defects.Displacement,deformation and strain have different definitions,but they can be easily calculated by corresponding equations.
