Multi-image display apparatus

A multi-image display apparatus comprising:

• a light source configured to emit light;
• a spatial light modulator configured to modulate the light emitted by the light source and generate image light;
• a first optical system configured to deliver the image light through a first light path and a second light path that is not parallel with the first light path;
• and
• a second optical system configured to deliver external light and the image light delivered through the second light path to a pupil of a viewer, through a third light path that is not parallel with the second light path,
• wherein the second optical system comprises a steering optical device provided at a crossing point of the second light path and the third light path and configured to be two-axis rotated, and
• wherein the first optical system further comprises:
• a first beam splitter configured to reflect a first linear polarization component of the light emitted by the light source toward the spatial light modulator and transmit light of a second linear polarization component modulated and reflected from the spatial light modulator;
• a second beam splitter provided at a first emission side of the first beam splitter, the second beam splitter being configured to reflect the light of the first linear polarization component toward the second light path and transmit the light of the second linear polarization component;
• a first lens provided between the spatial light modulator and the first beam splitter;
• a second lens provided between the first beam splitter and the second beam splitter;
• and
• a third lens provided at a second emission side of the second beam splitter.
