The measurement of particle field is important in science and engineering and the like fields. Interferometric particle imaging (IPI) technique is a relatively new particle measuring technique which can obtain the size and the location of particle by the interferogram of particle scattering light. The paper centers about the theory of the IPI technique and its application in spray field, the main work as follows has been done:
1. The basic theory of the IPI technique is studied based on geometrical opti...
