摘要： The invention is drawn to a method of using nanoparticle aggregates to form sensors and optical filters. Properly sized (60 and 200 nm) nanoparticle aggregates with cores having a sulfur-oxygen molecular species and a shell with a surface in contact with the core are obtained. Those nanoparticle aggregates have a first resonance profile to wavelengths between 350 nm and 1075 nm. A modified resonance profile for those nanoparticle aggregates is determined. The nanoparticle aggregates are then selectively sized by irradiating them with electromagnetic energy at sufficient intensity and spectral content to modify the first resonance profile towards the modified resonance profile. The resulting nanoparticle aggregates can be used as sensors or optical filters at a selected wavelength.

摘要： A configurable wavelength multiplexing device having first, second, and third reflectors. The first reflector has a first state in which it transmits incoming light (having first and second wavelengths) along a first transmitted path and a second state in which it reflects the light along a first reflected path. The second reflector reflects the first wavelength and transmits the second wavelength. The third reflector reflects the first wavelength. The first, second, and third reflectors are oriented so that when the incoming light is transmitted along the first transmitted path, the first wavelength is reflected by the second and third reflectors to travel along second and third reflected paths, the third reflected path intersects the first reflector at an angle such that the first wavelength is transmitted by the first reflector and continues on the first reflected path, and the second wavelength is transmitted by the second reflector.

摘要： The present invention provides a liquid crystal display apparatus and a method for viewing liquid crystal displays over a wide range of viewing angles with minimal loss in image contrast and gray level. Prior art liquid crystal displays (LCDs) exhibit low contrast and gray level inversion when viewed at large viewing angles. Prior art solutions to these problems include using a phase retardation plate or film interposed between the liquid crystal layer and a polarizer layer as an optical compensator. While such a solution improves image contrast and reduces some undesirable angular effects, the fabrication of such phase retardation compensator films requires precise thickness control and is expensive. The present invention discloses that by tilting the absorption axis of the birefringent polymer molecules comprising the polarizer sheet to orient at an appropriate angle relative to the liquid crystal image display panel, the contrast ratios and the gray level stability are substantially improved for wide angle viewing. For projection displays, absorption axis tilting (tilting) can be done by simply tilting the plane of a standard polarizer sheet relative to the plane of the LC image display. For flat panel displays, tilting can be accomplished by using a new type of sheet polarizer in which the long axis of the parallel chains of polymer molecules within the sheet are tilted relative to the physical plane occupied by the polarizer sheet and the adjacent coplanar liquid crystal layer.
摘要翻译：本发明提供了一种液晶显示装置和用于在宽范围的视角上观看液晶显示器的方法，其中图像对比度和灰度级的损失最小。现有技术的液晶显示器（LCD）在大视角观看时表现出低对比度和灰度级反转。对于这些问题的现有技术方案包括使用介于液晶层和偏振器层之间的相位延迟板或膜作为光学补偿器。虽然这样的解决方案提高了图像对比度并减少了一些不期望的角度效应，但是这种相位延迟补偿膜的制造需要精确的厚度控制并且是昂贵的。本发明公开了通过使包含偏振片的双折射聚合物分子的吸收轴相对于液晶图像显示面板以适当的角度倾斜，对于广角观察，对比度和灰度稳定性显着提高。对于投影显示，吸收轴倾斜（倾斜）可以通过简单地倾斜标准偏振片的平面相对于LC图像显示的平面来进行。对于平板显示器，倾斜可以通过使用新型薄片偏振器来实现，其中片材内的聚合物分子的平行链的长轴相对于偏振片所占据的物理平面和相邻的共面液晶层。
