Patent ID: 11947316
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. 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 reflective spatial light modulator configured to reflect and modulate the light emitted from the light source,
wherein the optical system comprises:
a first beam splitter configured to reflect the light emitted from the light source towards the spatial light modulator and to transmit the light reflected from the spatial light modulator;
a first mirror configured to reflect the light transmitted from the first beam splitter;
a second beam splitter provided in the second direction from the first mirror; and
a second mirror configured to reflect light reflected from the second beam splitter,

wherein the first mirror is further configured to reflect the light transmitted from the first beam splitter toward the second beam splitter in the second direction.
