摘要： An image forming device for use in an optical projection device includes an optical interface and an array of movable elements selectively movable toward or away from the optical interface to selectively locally frustrate total internal reflection at the optical interface such that light totally internally reflected at the optical interface defines an image. A projection display device includes an optical projector system including the image forming device.

摘要： The inventive dummy load is mounted on the input power cables of a traffic signal while managing the heat load generated by either a resistive and/or capacitive load. Using the inventive dummy load, there is no thermal path back to the light emitting diode (LED) board. The inventive dummy load may be easly installed, removed, or replaced. The dummy load can be retrofit to adapt to a new controller, either by adding to or replacing the dummy load after initial installation or by removing part or all of the dummy load. There is no need to breach the sealed lamp to adjust the dummy load. Thus, field-adjustments can be made. Further, the number of parts required to manufacture lamps for a variety of retrofit applications are reduced, which in turn reduces the cost and complexity of the lamp.

摘要： A lighting apparatus (10) includes a wave guide (14) formed from a translucent material. The wave guide has a top surface (30), a bottom surface (32) that has a pre-defined curvature, and at least one side surface (34) that receives light (40) injected therein. A plurality of microstructures (36) is arranged on selected areas of the bottom surface (32) of the wave guide (14). The plurality of microstructures (36) cooperates with the pre-defined curvature of the bottom surface (32) to scatter at least a portion of the light (40) injected into the at least one side surface (34). The scattered light (42) exits the wave guide (14) through the top surface (30). At least one light emitting diode (16) injects light (40) into the at least one side surface (34) of the wave guide (14). The scattered light (42) that exits the wave guide (14) forms at least one symbol viewable by an associated observer.

摘要： In an SLM-type display system, a solid state light source can be used to augment a lamp light source in a least two different ways. First, a solid state source can be used to augment deficiencies in a particular spectral region. Typically, lamps are deficient in red, and a red solid state source would be used. However, the same concept applies to augmenting any color region. Multiple solid state sources could be used to augment more than one region. Second, when the SLM system uses a color wheel, a solid state source can be used to eliminate “spoke loss”. Multiple solid state sources can be used for providing different colors during the spokes.

摘要： A single-mode semiconductor laser for optical pumping in H.sup.e and .sup.4 He and high-sensitivity magnetometers based upon these systems. A distributed Bragg reflection (DBR) or distributed feedback (DFB) single mode, preferably InGaAs laser diode (1) which obviates the need for optomechanical arrangements and their inherent instabilities as required by the prior art laser pumped magnetometers. By constructing a DBR or DFB region (28) within the laser diode structure, the laser is forced to operate within a single-mode at a wavelength that is jointly determined by the gain of the laser medium and feedback from the Bragg grating. This wavelength is controllable in one of three ways: (1) temperature control (13) of the laser diode junction and grating, (2) injection current control (12) within the gain region, (3) current control (11) of the Bragg grating region or any combination of the three. An alternative approach is to use the Fabry-Perot device and introduce an external grating control, if proper coatings are applied to the laser faces.
摘要翻译：基于这些系统的用于He和4He的光泵浦的单模半导体激光器和高灵敏度磁力计。分布式布拉格反射（DBR）或分布式反馈（DFB）单模，优选为InGaAs激光二极管（1），其消除了对现有技术的激光泵浦磁力计所要求的光机械布置及其固有不稳定性的需要。通过在激光二极管结构内构造一个DBR或DFB区域（28），激光器被迫在波长为单一模式下工作，该波长由激光介质的增益和来自布拉格光栅的反馈共同决定。该波长可以通过以下三种方式之一进行控制：（1）激光二极管结和光栅的温度控制（13），（2）增益区内的注入电流控制（12），（3）电流控制（11）布拉格光栅区域或三者的任意组合。另一种方法是使用法布里 - 珀罗（Fabry-Perot）器件并引入外部光栅控制，如果适当的涂层应用于激光面。
