摘要： An optical device consists of one or more optical waveguides and mechanical light switches 30. When a light switch 30 is turned on, it extracts light beam 62a from a waveguide core 20 and redirect the light beam 62b into free space, it redirects an incoming light beam 80 from free space and injects the light beam 80a into the waveguide core 20, or it performs both functions at the same time, depending on specific applications. On and off states of a light switch 30 are achieved by pulling the light switch 30 into a close vicinity of the waveguide core 20 and by pushing the light switch 30 away from the waveguide core 20, respectively. An interactive fiat-panel display can be built based on this invention. A plurality of parallel channel waveguides forms a display panel. An array of light beams 62a, injected from an array light source 60, propagates along waveguide cores 20 until reaches a location where a light switch 30 is turned on. At this location, the light switch 30 redirects the light beams towards a viewer. An image is produced when the light switches 30 are turned on sequentially while the light-intensity distribution on the array light source 60 is synchronically updated. The panel display is capable of responding to an input optical signal by detecting an incoming light beam 80 from a light pen 100. An array of photodetectors 81 is used to identify the location of the incoming light beam 80 on the display panel and a computer is used to execute a corresponding action accordingly.
摘要翻译：光学装置由一个或多个光波导和机械光开关30组成。当光开关30接通时，它从波导芯20提取光束62a并将光束62b重定向到自由空间中，从而将入射光光束80从自由空间注入，并将光束80a注入到波导芯20中，或者根据具体应用同时执行两个功能。通过将光开关30拉到波导芯20的紧密附近并分别将光开关30推离波导芯20来实现光开关30的接通和断开状态。可以基于本发明构建交互式平板显示器。多个并行通道波导形成显示面板。从阵列光源60注入的光束阵列62a沿着波导芯20传播，直至到达光开关30导通的位置。在该位置，光开关30将光束朝向观察者重定向。当在同时更新阵列光源60上的光强度分布的同时顺序地接通光开关30时，产生图像。面板显示器能够通过从光笔100检测入射光束80来响应输入光信号。光电检测器81的阵列用于识别入射光束80在显示面板上的位置，计算机是用于相应地执行相应的动作。

摘要： A microstructure for steering light is provided that may be stepwise controlled to provide tilt positions in two dimensions. The arrangement is two-dimensional since a tilt axis may be defined as the axis along which the base is tilted to move from one of the two tilt positions to the other. At least one additional tilt position is provided that cannot be reached from either of those two tilt positions by tilting the micromirror assembly along the tilt axis. Instead, such an additional tilt position requires that there at least be a tilt component in a direction orthogonal to the tilt axis.

摘要： An optic switching system and method are presented for controllably directing an incident beam of electromagnetic radiation propagating with a certain solid angle from a primary optical waveguide to a predetermined secondary optical waveguide. A primary reflective concave surface is disposed for receiving the incident beam, reflecting the incident beam and focusing a reflected beam at a primary focusing place. A secondary reflective concave surface having a radius less than a radius of the primary reflective concave surface is disposed for receiving the beam reflected by the primary reflective surface and reflecting this beam to the predetermined secondary optical waveguide. The secondary reflective concave surface is disposed at the place located downstream of the primary focusing place with respect to the direction of propagation of the beam reflected from the primary reflective concave surface. An actuator is operatively connected to one of the reflective surfaces or to both and is adapted for controlling a selective displacement of the respective reflective surface relative to the optical beam that impinges thereon.

摘要： The present invention provides an optical switching element causing less loss of light and permitting high response, thinning of an optical system for illumination, and the realization of an image display device exhibiting precise grayscale properties. In the optical switching element, an extraction surface of a light extraction unit mounted to a thin film is brought into contact with the total reflection surface of a light guide serving as a light guide unit comprising a glass plate or the like for transmitting light by total reflection, or near at a distance from the total reflection, surface for allowing extraction of evanescent waves, to extract the incident light transmitted through the light guide and emit the extracted light to the outside through an emission member. Such optical switching permits the light extract unit to be operated in a range of approximately a wavelength or half a wavelength, thereby providing an optical switching element capable of high-speed operation and having high contrast because the incident light does not leak due to total reflection during an off time.

摘要： An optical switch comprised of an artificial muscle activation material that is adhered longitudinally around an optical channel, such as an optical fiber or group of fibers, to cause the channel to undulate in 2-½ dimensions when the material is activated by a voltage source via electrodes on the surface of the artificial muscle activation material. The material can be applied to the optical channel in a series of longitudinal strips or as a jacket surrounding the channel. When activated by a voltage source, be it a constant source or a variable source varying in amplitude, frequency or polarity, the artificial muscle material bends, causing the optical channel to also bend. The artificial muscle activation material can be formed into an optical channel itself when formed into a channel and cladded to have internal reflection.
