Abstract
In the present invention, by providing a hologram displaying apparatus including a light source configured to emit input light, a spatial light modulator configured to modulate the input light into diffracted light, and a plurality of noise filtering elements configured to remove optical noise components from the diffracted light modulated by the spatial light modulator, and display a hologram, an optical path of a light source for displaying the hologram can be drastically reduced while effectively performing spatial filtering.
