Abstract:
An apparatus for displaying a holographic three-dimensional (3D) image is provided. The apparatus includes: a holographic pattern generation unit; a spatial optical modulation device including a phase transition layer formed of a phase transition material, a phase of which is changed by a temperature. A holographic pattern generated by the holographic pattern generation unit is optically addressed on the spatial optical modulation device. The apparatus also includes a heat source for applying heat to the phase transition layer; a control unit for controlling the heat source according to holographic pattern information generated by the holographic pattern generation unit; and a reproduction light source for irradiating light for image reproduction onto the spatial optical modulation device.
Abstract:
A display employing a signal transmission scheme using an optical interconnection together with an electrical interconnection is provided. The display includes a screen including a plurality of sub displays configured to display information, a plurality of sub signal processors electrically connected to the plurality of sub displays, the sub signal processors being configured to perform conversion between an optical signal and an electrical signal, and a main signal processor optically connected to at least a portion of the plurality of sub signal processors.
Abstract:
Provided are examples of light modulators and optical apparatuses that may include the light modulators. A light modulator may include a plasmonic nano-antenna and an element for changing plasmon resonance characteristics of the plasmonic nano-antenna. The plasmon resonance characteristics of the plasmonic nano-antenna may be changed due to a change in refractive index of the element, and thus light may be modulated.
Abstract:
An image processing apparatus and method include a receiver configured to receive an image, a display configured to display the received image, an extractor configured to extract a first object contour by applying a preset algorithm to an area of the displayed image designated by a user and extract a second object contour based on the designated area, an image analyzer configured to analyze the displayed image, and a controller configured to determine weight values for the first and second object contours based on an analysis result of the image analyzer and extract an object contour based on the first and second object contours to which the determined weight values are applied. The image processing apparatus extracts an object intended by a user even in a heavily noisy image.
