A speckle simulation model based on the angular surface scattering from the analyzed rough surface is proposed for laser applications. For computationally efficient simulation model for the far-field and large-area screen, the generalized Harvey−Shack theory was used to calculate the angular scattering of rough surface that was geometrically analyzed considering the roughness and the lateral correlation length. A laser display was selected as a reference system to validate the simulation result and it was found that the proposed simulation model can generate almost similar speckle patterns with a speckle contrast ratio of 0.7095 compared to that of 0.7066 from experimental measurement.
