Abstract

A method to neutralize the diffraction halo effect in speckle photography is presented. A negative of the halo is used in the fringe observation plane to achieve this goal. Experimental irradiance distributions as well as Young’s fringes with and without the negative mask are presented. It is shown that the apodization procedure is effective in solving the problems caused by varying the diffraction halo irradiance.
