Abstract: The error model of classical Moire tomography is analyzed.The applicable range of current reconstruction method is limited through analyzing causes of the error.Reconstruction results of experimental temperature fields using classical Moire tomography are compared with real measured values to verify the error model.The key problem existing in conventional Moire tomography is analyzed and an method of wavefront retrieving based on phase unwrapping is presented.
