An acousto-optic device capable of increasing a range of a diffraction angle of output light by using a nanostructured acousto-optic medium, and an optical scanner, an optical modulator, a two-dimensional/three-dimensional (2D/3D) conversion stereoscopic image display apparatus, and a holographic display apparatus using the acousto-optic device. The acousto-optic device may include a nanostructured acousto-optic medium formed by at least two different mediums repeatedly alternating with each other, wherein at least one of the at least two different mediums includes an acousto-optic medium. The acousto-optic device having the aforementioned structure may increase the range of a diffraction angle of output light. Thus, various systems such as the optical scanner, the optical modulator, the 2D/3D conversion stereoscopic image display apparatus, and the holographic display apparatus may not require a separate optical system to increase an operational angle range, thereby decreasing a size of the system and/or improving a resolution of the system.

Nanostructured acousto-optic device, and optical scanner, optical modulator, and holographic display apparatus using the nanostructured acousto-optic device

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.

Provided are a light guide member, a lighting apparatus including the light guide member, and a method of fabricating the light guide member. The light guide member comprises: a body, which is formed as a transparent plate, including a first surface and a second surface facing the first surface; and a plurality of dimple type optical controllers formed beneath at least one of the first surface and the second surface and having reflective surfaces that reflect light proceeding between the first and second surfaces of the body toward at least one of the first and second surfaces.

An electronic device for detecting a position of an object is disclosed, The electronic device includes an optical source configured to emit light to a detection area, a light concentrator configured to concentrate light reflected by a target object located in a detection area, a light receiver configured to receive through photodiodes the reflected light concentrated by the light concentrator and to output a light quantity pattern of the reflected light, and a processor configured to determine the position of the target object based on the light quantity pattern of the reflected light.

Device and method for detecting position of object

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.

OASLM-based holographic display

A complex spatial light modulator and a three-dimensional (3D) image display apparatus including the complex spatial light modulator are provided. The complex spatial light modulator includes: a spatial light modulator that modulates a phase of light; a prism array including a plurality of prism units, each of the plurality of prism units including a first prism surface and second prism surface, where light from the spatial light modulator is incident on the prism array; and a polarization-independent diffracting element that diffracts light that has passed through the prism array.

A complex spatial light modulator for modulating a phase and amplitude of a light beam and a 3-dimensional (3D) display including the same are provided. The complex spatial light modulator includes a spatial light modulator modulating a phase of a light beam, a lenticular lens array disposed next to the spatial light modulator, and a volume holographic lens array spaced apart from the lenticular lens array and allowing light beams output from the lenticular lens array to be superimposed and to interfere with each other, and so that the phase and an amplitude of the light beam are simultaneously modulated.

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.
