Multi-image display apparatus providing holographic image

A multi-image display apparatus comprising:

• a light source configured to emit light;
• a spatial light modulator configured to provide a first image by modulating the light emitted from the light source;
• and
• an optical system configured to transmit the first image provided by the spatial light modulator to a viewer,
• wherein the optical system is configured such that a first travelling path of the first image provided by the spatial light modulator comprises a first optical path in a first direction, a second optical path in a second direction orthogonal to the first direction, and a third optical path in a third direction orthogonal to the first direction and the second direction,
• wherein the optical system is configured such that the first image and a second image provided from a second travelling path different from the first travelling path are provided to the viewer along the third optical path,
• wherein the spatial light modulator comprises a transmissive spatial light modulator configured to transmit and modulate the light emitted from the light source, and
• wherein the optical system further comprises:
• a second beam splitter configured to transmit the light provided from the spatial light modulator;
• a first lens and a second lens provided between the spatial light modulator and the second beam splitter;
• and
• a spatial filter provided between the first lens and the second lens.
