The invention discloses an information acquisition lens array plate, which is used for a holographic three-dimensional display system and comprises a plate body and M*N lenses with consistent imagingparameters, wherein the lenses are arranged on the plate body and have parallel optical axes, M and N are integers and are greater than 1, and M*N lenses with consistent imaging parameters are used for sampling and acquiring M*N spatial spectrum images Imn of an object O to be displayed in three dimensions, M is equal to 1 to M, N is equal to 1 to N, wherein the spatial sampling angle is omega mn=d1/l1, d1 is the central distance between the lenses, and l1 is the distance between the information acquisition lens array plate and the object O. The information acquisition lens array plate effectively overcomes the inherent contradiction between the imaging quality of the micro-lens array and the resolution of the three-dimensional image displayed by the micro-lens array in the integrated photography, realizes the holographic coding and holographic display of three-dimensional space information, and obtains perfect true three-dimensional display visible to human eyes.
