The Droplet Distribution of Three Dimensional Spray by In-Line Holography Theory with Large Depth of Field

The paper discusses the theory of recording droplet distribution in spray field by holography in detail and then infers parts of calculations, which raise its ability of predictation in practice. Forsolving one of the problems-determining the large depth of field in droplet distribution in spray field, an efficient solution-tomographic and holographic recording method is given.This paper fully discusses the design on optical system, and gives the optimal scheme on recording by spherical wave and reconstructing by plane wave, which raises practical ability of the holography.
