    摘要: A detection system. The detection system includes a substrate, a laser, and a sensor array. The substrate includes a first surface, a second surface conceptually divided into multiple areas, and a third surface. The laser is configured to emit electromagnetic radiation into the substrate and incident subsequently onto second surface areas. The sensor array is configured to capture electromagnetic radiation reflected from the second surface. If a first dielectric, having first dielectric constant, is in contact with some areas, electromagnetic radiation incident thereon experiences total internal reflection and if a second dielectric having second dielectric constant is in contact with other areas, some of the electromagnetic radiation incident thereon is reflected back into the substrate by the second dielectric. The sensor array is configured to detect laser speckle originating from the incidence of the electromagnetic radiation at the second surface and to detect electromagnetic radiation reflected from the second dielectric.

    摘要: This disclosure provides systems, methods and apparatus for measuring the direction distribution of light. In some implementations, an ambient light direction distribution sensor device can include, for example, a light steering layer that is designed to steer light from different incident angles toward associated locations on a light detector. The light detector can then output one or more signals that are indicative of the amount of light that is incident upon the sensor device from different incident angles. These measurements can be used to control various parameters of a display in response to the detected ambient lighting conditions.

    摘要: Modulator devices are selectably adjustable between at least two states, wherein the transmission and/or reflection of particular wavelengths of light are modified. Certain modulator devices are substantially uniformly adjustable over a wide range of wavelengths, including visible and infrared wavelengths. Other modulator devices are adjustable over visible wavelengths without significantly affecting infrared wavelengths. In addition, the modulator devices may be used in conjunction with fixed thin film reflective structures.

    摘要: Tunable cross-coupling evanescent mode optical devices and methods of making the same are described. In one aspect, a tunable optical device includes a first layer, a second layer, a metal layer disposed between the first and second layers, and an electrode. The first layer is supportable of electromagnetic field modes over a range of wavelengths that includes a target wavelength range. The second layer is disposed between the metal layer and the electrode and has an index of refraction that is adjustable over a range of values. The metal layer is disposed between the first and second layers and has at least one corrugated metal film region with a corrugation periodicity enabling cross-coupling of evanescent modes of equal wavelength within the target wavelength range and localized on opposite sides of the metal layer with different respective wavenumbers. The cross-coupling evanescent modes have a cross-coupling wavelength determined at least in part by the corrugation periodicity and the index of refraction of the first and second layers and is substantially unaffected by the electrode.

    摘要: A detection method is integrated with a filtering method and an enhancement method to create a fluorescence sensor (10) that can be miniaturized. The fluorescence sensor (10) comprises a thin film geometry including a waveguide layer (16), a metal film layer (20) and sensor layer (32). The thin film geometry of the fluorescence sensor allows the detection of fluorescent radiation over a narrow wavelength interval. This enables wavelength discrimination and eliminates the detection of unwanted light from unknown or spurious sources.

    摘要: A front light guide panel including a plurality of embedded surface features is provided. The front light panel is configured to deliver uniform illumination from an artificial light source disposed at one side of the font light panel to an array of display elements located behind the front light guide while allowing for the option of illumination from ambient lighting transmitted through the light guide panel. The surface embedded surface relief features create air pockets within the light guide panel. Light incident on the side surface of the light guide propagates though the light guide until it strikes an air/light material guide interface at one on the air pockets. The light is then turned by total internal reflection through a large angle such that it exits an output face disposed in front of the array of display elements.
