摘要： Solar energy concentrator architectures employ an array of electro-optical liquid prism modules to deflect sunlight onto PV cells. Without any mechanical moving parts, the dynamic liquid prism allows the concentrator to adaptively track the daily changes of the sun's orbit. The liquid prism modules may be arranged, for example, into a sheet-shaped beam steering array; a condenser device such as a Fresnel lens is then used to focus the light deflected by the modules onto one or more PV cells—preferably CPVs. Another possible concentrator architecture requires arranging a plurality of liquid prism modules into a semi-spherical pattern, such that light impinging on the modules is directed onto one or more PV cells or CPVs.

摘要： Interferometric modulators may include a movable layer including both permanently anchored and programmable hinges. Unactuated programmable hinges may exert little or no force on the movable layer. When actuated, programmable hinges may exert a mechanical force on the movable layer in a direction approximately opposite to the direction of force exerted by the permanently anchored hinges. By increasing a voltage between the programmable hinges and an electrode, a progressive number of programmable hinges may be engaged. The mechanical force exerted on the movable layer by these hinges may change the relative position of the movable layer within an IMOD device.

摘要： A two-stage drive waveform switches a DFLC from a high tilt state such as above the LC's linear region or near the ‘saturated’ or ‘field-driven homeotropic’ state of the LC to a low tilt state quickly and without scattering. A relaxation voltage is applied to delay the onset of the high amplitude high frequency kick voltage when switching from a high tilt state to a low tilt state. The relaxation voltage allows the molecules to ‘relax’ in accordance with their own elasticity towards their low tilt state in the direction of the average azimuth angle of the low tilt state. Once the tilt angle has relaxed sufficiently, the kick voltage is applied to drive the molecules quickly to the low tilt state. Most unexpectedly, optimal switching time and the desired molecular response is achieved by delaying the onset of the large kick voltage via application of the relaxation voltage. The relaxation voltage may constitute a lower amplitude holding voltage, a small or zero DC voltage or a smooth windowing of the kick voltage. Whether to apply the relaxation voltage at all and how to apply the relaxation voltage for optimal switching are suitably controlled as a function of the high tilt state. The DFLC is suitably switched from the low-to-high tilt state in the conventional manner without application of a relaxation voltage.

摘要翻译： 两级驱动波形将DFLC从LC倾斜状态（例如高于LC的线性区域）或接近LC的“饱和”或“场驱动垂直”状态切换到低倾斜状态，并且不发生散射。 当从高倾斜状态切换到低倾斜状态时，施加弛豫电压以延迟高幅度高频踢脚电压的开始。 松弛电压允许分子在低倾斜状态的平均方位角的方向上根据它们自身的弹性朝着它们的低倾斜状态“松弛”。 一旦倾斜角度已经充分放松，就施加踢击电压以将分子快速地驱动到低倾斜状态。 最意想不到的是，通过施加弛豫电压延迟大的踢脚电压的开始来实现最佳的开关时间和期望的分子响应。 弛豫电压可以构成较低的振幅保持电压，小的或零的直流电压或踢脚电压的平滑窗口。 作为高倾斜状态的函数，适当地控制是否施加弛豫电压以及如何施加用于最佳切换的弛豫电压。 DFLC适当地从常规方式从低到高倾斜状态切换，而不施加松弛电压。

摘要： An electronically adjustable color filter device is provided for filtering light at a wavelength corresponding to a selected color of the Electromagnetic Spectrum. Unpolarized light, at the specified wavelength, is polarized using a dichroic, cholesteric polarizer. An adjustable wave plate is optically aligned with the polarizer to convert the polarized light into two separate elements, each element having a different polarization state. A color filter, which may be a dichroic cholesteric film, filters one element of the polarized light while permitting the second element to pass. A plurality of the color filter devices may be positioned sequentially to filter various colors of light, thereby producing light having a desired combination of colors. Polarized light may be filtered, whereby a polarizer is not required. An electronically adjustable color filter system may include multiple filter devices, as well as a color detector and a controller for adjusting the wave plates.

摘要： An electronically adjustable, combinational color filter device is provided for generating color light. Incoming light is split in a polarizing beam splitter/combiner into a first and a second element of light. One or more wave plates operate to modify the polarization state of the first element of light, and one or more dichroic reflective filters reflect portions of the first element of light having a predetermined wavelength. Similarly, one or more wave plates operate to modify the polarization state of the second element of light, and one or more dichroic reflective filters reflect portions of the second element of light having a predetermined wavelength. Reflected portions of the first element and the second elements of light are combined in the polarizing beam splitter/combiner to create color light. A spatial light modulator may be used to create color images.

摘要： A switchable apochromatic polarization rotator is provided. A first fixed waveplate has a first principal axis fixed in a first orientation. A second fixed waveplate has a second principal axis fixed in a second orientation. First and second switchable waveplates have principal axes oriented such that broad spectral range electromagnetic radiation transmitted through all of the waveplates has a first rotated polarization, wherein, in response to one or more control signals applied to the switchable waveplates, the principal axes of the switchable waveplates rotate such that the electromagnetic radiation transmitted through all of the waveplates has a second rotated polarization. The switchable waveplates utilize ferroelectric liquid crystal material, nematic liquid crystal material, or be mechanically rotated to adjust for orientation of their principal axes. Utilizing waveplates as described may be used to tune for a desired spectral range and/or compensate for temperature dependencies.

摘要： An OAOA measurement system uses optical elements to converge incoming light from multiple sources onto an FPA as respective crosshair patterns made from lines which are oblique with respect to the FPA's axes, such that each pattern's location indicates the angular position of its corresponding source. The optical elements are arranged such that each crosshair's center point is at least twice as bright as the lines which form the crosshair's arms. The position of each crosshair is interpolated by defining regions around each arm of one of the crosshairs, determining the points of peak intensity in each row or column within each region, and curve-fitting the points to define each arm. Multiple crosshair patterns are accommodated by assigning a small magnitude value to each pixel of a defined arm, and then repeating the interpolation process for another crosshair.
