The influence on image reconstruction of the coaxial holographic nonlinear recording for particles field was analyzed by using the threshold value function. In theory, the simulation model was built, in which the reconstructions of different shapes particles were recorded in the nonlinear segment of D-LogE. The effect of edge shearing appeared in the reconstruction. The simulation result and the experimental result are in good agreement. The result can develop the theory of the in-line holography. The effect of edge shearing not only offer the optic method for the image manipulation in the particle in-line holography but also shorten the time of image.
