The invention relates to a field-depth-variable and multi-view space dynamic imaging laser endorsement system and method. One or more wedge-shaped prisms are additionally arranged in a light path and the three-dimensional floating imaging customized view endorsement is realized under the action of deflecting light by the wedge-shaped prisms. Meanwhile, an inclined-plane or spherical-surface diffusion sheet is arranged in an original light path so that the continuous change of endorsement focal depth can be realized, and the change slope and the linearity can be customized according to the shape of the diffusion sheet; and as the realization method is performed, an endorsement effect with a field depth variable effect can be obtained. If two optical devices are arranged in the system at the same time, the endorsement of a field-depth-variable and multi-view three-dimensional floating imaging figure can be realized. The method and the system are simple in realization structure and high in endorsement efficiently; and the two effects are combined and the movement of a two-dimensional platform is matched, so that the figure endorsement with a plurality of special effects can be realized and the new industrial application of laser endorsement is brought.
