    Abstract: Provided are an acousto-optic element, an acousto-optic element array, and a display apparatus including the acousto-optic element array. The acousto-optic element includes: an acousto-optic modulator which includes an acousto-optic layer formed of an acousto-optic material; a light supplier which supplies light to the acousto-optic modulator in a first direction; a first sound-wave modulator which applies first elastic waves to the acousto-optic modulator in a second direction; and a second sound-wave modulator which applies second elastic waves to the acousto-optic modulator in a third direction. The light supplied from the light supplier to the acousto-optic modulator is deflected by diffraction caused by the first elastic waves applied from the first sound-wave modulator and diffraction caused by the second elastic waves applied from the second sound-wave modulator, and is output from the acousto-optic modulator through a front side of the acousto-optic modulator.

    Abstract: Provided is an optically addressable spatial light modulator (OASLM)-based holographic display and a method of operating the same. The display includes an addressing unit including a light source unit emitting a plurality of recording beams, a driving mirror array including driving mirrors that each reflect a recording beam incident thereon, and a mirror member array including mirror members that each obliquely reflect a recording beam incident thereon, in which each of the driving mirrors corresponds to one of the mirror members. The recording beams, which are transmitted by the addressing unit, are focused onto the OASLM by micro lenses of a lenslet array. The OASLM is optically addressed by the recording beams focused by the micro lenses of the lenslet array and thus modulates and diffracts a reproduction beam, incident thereon from a reproduction beam providing unit, and thus a holographic image is reproduced.

    Abstract: Provided are an optically addressable spatial light modulator (OASLM) divided into a plurality of segments, and an apparatus and method for displaying a holographic three-dimensional (3D) image using the OASLM. The holographic 3D image display apparatus includes a first light source which emits a write beam, an electric addressable spatial light modulator (EASLM) which modulates the write beam emitted from the first light source according to hologram information regarding a 3D image, a second light source which emits a read beam, an OASLM which receives the write beam modulated by the EASLM and modulates the read beam emitted from the second light source according to hologram information included in the modulated write beam, a scanning optical unit which projects the write beam modulated by the EASLM onto the OASLM, and a Fourier lens which focuses the read beam modulated by the OASLM onto a predetermined space to form the 3D image.

    Abstract: An illumination unit is provided including a coherent light source; a projection optical element which focuses a light beam emitted from the coherent light source onto a focal plane; and a holographic optical element interposed between the coherent light source and the projection optical element, and having an interference pattern formed thereon. The holographic optical element diffracts the light beam emitted from the coherent light source and emits the diffracted light to the projection optical element. Here, the interference pattern on the holographic optical element may have information that diffracts the light beam and thereby cancels a diffraction of the light beam due to an aberration of the projection optical element.
