Disclosed are a device for forming a three-dimensional holographic image by using an aperiodically designed optical element and a method thereof. A three-dimensional holographic imaging device comprises: a light source emitting light; a spatial light controller for modulating the light projected from the light source; and an irregular optical element for modulating an incident light by refracting, diffracting, or reflecting the direction of the incident light in a plurality of directions as the modulated light is incident on the spatial light controller wherein the three-dimensional holographic image can be formed based on the light modulated by the optical element.
