Abstract
A holographic display system and a holographic display method are disclosed. By utilizing the shift of at least one of the light source module and the spatial light modulator, a holographic image can be provided to a plurality of stationary or moving observers over a wide range. The holographic display system includes a light source module for generating a coherent beam; a spatial light modulator for generating a holographic image using the coherent beam; a position detecting device for detecting an eye position of at least one observer; and an actuating device capable of shifting at least one of the light source module and the spatial light modulator based on the eye position of the at least one observer, thereby projecting the holographic image to the eye position of the at least one observer.
