Abstract
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.
