摘要: An optical device stack includes at least one of a photodetector or an optical emitter and a metasurface. The metasurface is disposed over a light-receiving surface of the photodetector or a light emission surface of the optical emitter. The metasurface includes a first conductive layer having an electrically-tunable optical property and an array of conductive nanostructures disposed on a first side of the first conductive layer. A second conductive layer is disposed on a second side of the first conductive layer. An electrical insulator is disposed between the first conductive layer and the second conductive layer. A change in an electrical bias between the metasurface and the second conductive layer, from a first electrical bias to a second electrical bias, tunes the electrically-tunable optical property from a first state to a second state, and changes an electrically-tunable optical filtering property of the metasurface.

摘要: Disclosed is a method and system for cost effective, convenient remote high fidelity color reproduction and matching that can be used to convey color to observers remote to the physical source of color. Such remote observers can include product consumers wishing to view a product color, for example. In a preferred embodiment, the method comprises capture of article or product reflectance spectra and the use of this spectrum to filter ambient light or directed light in the environment of a remote user. Other embodiments of methods include various techniques to capture product spectral information and color matching functions useful for color reproduction using colored light sources. Additional systems embodiments include devices exploiting multiprimary displays to render the product color in avoidance of metamerism.

摘要: A method for generating a control signal, having at least one frequency component, for an acousto-optical element, from one frequency spectrum having the at least one frequency, or from multiple frequency spectra which together have the at least one frequency, includes the step of obtaining, from the one frequency spectrum or from the multiple frequency spectra, one transmit signal in the time domain in each case via an inverse Fourier transform. The one or the multiple transmit signals are modulated via a single-sideband modulation onto a carrier signal having a carrier frequency in order to obtain one modulated signal in each case. The control signal is obtained as a real part of the one modulated signal or as a consolidation of the real parts of the multiple modulated signals.
