Abstract:
A system and a method for a transaction based on a license plate number. A method of providing data for paying for an item, performed by a mobile device, includes receiving a license plate number from a vehicle terminal through short-range wireless communication, selecting a credit card to be used to pay for an item provided in an offline store, and transmitting the received license plate number and information regarding the selected credit card to a payment server. The license plate number and the information regarding the selected credit card transmitted to the payment server are used for the payment server to authenticate the payment of the item, together with information regarding a license plate number provided from a store terminal of the offline store to the payment server.
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 optical apparatus includes a touch substrate; a waveguide layer arranged on the touch substrate, the waveguide layer including a plurality of waveguides; an optical output structure arranged on the waveguide layer and configured to output light propagating in the plurality of waveguides at touched locations on the touch substrate; a gap layer arranged to provide a predetermined gap between the waveguide layer and the optical output structure; and an optical system, which projects light output by the optical output structure.
Abstract:
A spatial light modulator, a holographic image display including the same, and a method for spatially modulating light. The spatial light modulator modulates a phase of light that is incident on a plurality of pixels and includes a variable refractive index layer that has a refractive index which is variable based on one of an optical signal and an electrical signal, and a metal layer that is disposed on the refractive index-change layer, and a high refractive index layer on the metal layer. Light incident on the metal layer causes generation of a surface plasmon at an interface between the variable refractive index layer and the metal layer.
