【Abstract】 The theory of measuring the droplet distribution field of diesel engine injection spray with laser holography is analysed and the formulate of the holography are deduced. The problems of the measured, the depth of field and density of the field are discussed in detail. The theoretical basis is founded for the measurement.更多还原
