Projection moire deflectometry for mapping phase objects
This paper presents a novel method based on projection moire deflectometry for the visualization and quantitative evaluation of full-field density and temperature variations in phase object. The basic principle and operation of this optical system are discussed. The measurement for phase object by method is given. The proposed setup is characterized by its simplicity, in-expensiveness and versatility. It can handle large observation areas. These facts make it attractive in flow visualization, heat and mass transfer measurements.
