SEE-THROUGH HOLOGRAPHIC DISPLAY APPARATUS

摘要

A see-through holographic display apparatus includes a relay optical system expanding or reducing and transferring a hologram image generated by a spatial light modulator, a noise removal filter removing noise from diffraction light of the hologram image transferred through the relay optical system, and a light path converter changing at least one of a path of the diffraction light of the hologram image transferred from the relay optical system and a path of external light.

主权项

1. A see-through holographic display apparatus comprising:
a light source configured to emit light; a spatial light modulator configured to diffract the emitted light and generate a hologram image by modulating the emitted light; a relay optical system configured to expand or reduce the generated hologram image, and transfer the expanded or reduced hologram image; a noise removal filter configured to remove noise from diffraction light of the transferred hologram image; and a light path converter, on which an external light and the diffraction light are incident and which is configured to change a path of the diffraction light, and transfer at least one among the diffraction light and the external light to a same region.
