A new monolithic resonator metasurface design achieves ultra-high Q-factors while using only one resonator per unit cell. The metasurface relies on breaking the symmetry of otherwise highly symmetric resonators to induce intra-resonator mixing of bright and dark modes (rather than inter-resonator couplings), and is scalable from the near-infrared to radio frequencies and can be easily implemented in dielectric materials. The resulting high-quality-factor Fano metasurface can be used in many sensing, spectral filtering, and modulation applications.

The invention claims a terahertz band metamaterial sensor based on quasi-electromagnetically induced transparency (quasi-EIT) effect. The terahertz band metamaterial sensor comprises a dielectric layer and a metamaterial of a sub-wavelength metal array on the dielectric layer, wherein the sub-wavelength metal array is composed of a plurality of open circular resonant rings and open square resonantrings. Under the excitation of terahertz waves, the open circular resonant rings and the open square resonant rings separately exhibit a bright mode and a dark mode; when the two resonant rings are combined and the space between the two is 80.0-85.0 micrometers, the bright and dark modes are coupled to each other, destructive interference is generated, realizing the quasi-EIT effect is realized,and sharp transmission peaks are produced near resonance points. The sensitivity of the terahertz band metamaterial sensor is measured according to the amount of translation of the frequency of the sharp transmission peaks generated by the quasi-EIT effect in the transmittance spectrum within the unit refractive index change, so as to realize the refractive index sensing function in the frequencyrange of 400 GHz to 800 GHz.

The present invention discloses shutter glasses and a 3D display system. The shutter glasses include a first polarizer, a second polarizer, a normally-white LCD panel, and a normally-black LCD panel. A thickness of the normally-white LCD panel is not the same as a thickness of the normally-black LCD panel, and an optical compensation film is installed between the first polarizer and the liquid crystal layer of the normally-black LCD panel and/or between the second polarizer and the liquid crystal layer of the normally-black LCD panel in order to compensate for a dispersion occurred when the liquid crystal layer of the normally-black LCD panel is in a dark mode. In this way, the present invention can not only shorten the response time of the shutter glasses to reduce the power consumption, but also reduce the 3D crosstalk.

An automatic darkening and glare reducing liquid crystal mirror for vehicles is disclosed. The mirror has a front substrate (101) of transparent glass or plastic and a back substrate (109) of glass orplastic with a highly reflective or transflective mirrored coating (108). The front and back substrates are spaced apart a small distance to define a liquid crystal cell between the substrates and aliquid crystal fluid (106) incorporating dichroic dyes is contained within the liquid crystal cell. A conductive thin film (102) is applied onto the interior surface of the front substrate and the reflective or transflective coating (108) of the back substrate also is conductive. An alignment compound is deposited on the conductive thin film (102) and on the reflective or transflective coating (108) and the alignment compound bounds the liquid crystal cell. An electronic control circuit is adapted to apply selectively a voltage signal to the conductive thin film and the reflective or transflective coating (108) to affect the transmittance of the liquid crystal fluid, and thereby the darkness of the mirror. The nature of the alignment compound determines a home or rest alignment of the liquid crystal molecules, either parallel or perpendicular to the substrates, and thus determines whether the mirror is normally dark (a 'dark mode' mirror) or normally bright (a 'bright mode' mirror). Application of a voltage signal to a dark mode mirror lightens it while application of a voltage signal to a bright mode mirror darkens the mirror. A headlight sensor (302) and an ambient sensor (301) are coupled to the electronic control circuit and the circuit is configured to darken the mirror in response to signals from the sensors indicating that the ambient light intensity is below a predetermined threshold (equivalent to nighttime) and the intensity of light from headlights impinging on the mirror is above a predetermined threshold (equivalent to a glare condition).
