An optical system is disclosed. The optical system includes a fluid. A container is filled with the fluid, and the container has at least one window for permitting subject light to enter the container. At least one optical element is disposed within the container for performing a predetermined optical function on the subject light. The fluid has a viscosity of no greater than 40 centistokes and the optical element has an index of refraction approximately the same as the fluid. The fluid provides increased transmission of blue light as a percentage of total light being transmitted.

Optical fluid for projection prism

An optical system is provided that has an enclosure which is substantially filled with a fluid. The enclosure also has an aperture for receiving an electromagnetic wave that is altered by an optical component contained in the enclosure. The enclosure also has an aperture mask and blocker that are at least partially immersed in the fluid.

Internal aperture mask for embedded optics

An optical system including a transparent fluid and a container filled with the fluid as well as at least one optical element having an index of refraction which approximately matches that of the fluid. The fluid is chosen to have a viscosity no greater than 40 centistokes. As a result, the low viscosity of this optical fluid reduces thermal irregularities. Also, improved transmission, particularly in the blue spectrum is achieved as compared to conventional optical fluids.

A liquid crystal light valve device exhibiting improved performance capabilities fabricated using a cadmium telluride light blocking layer doped with nitrogen. Because of the incorporation of nitrogen into the cadmium telluride light blocking layer, the layer can be applied using high-speed, low-cost sputtering techniques without resulting in excessive photoconductivity or photoshading. The cost of the addition of nitrogen is minimal. The process of the present invention is amenable to precise control and wide flexibility which results in control of the quality aspects of the light blocking layer such as particulate density.

There is disclosed a dielectric reflector for selective wavelength reflection which comprises an alternately deposited series of thin films of silicon and silicon dioxide layers respectively arranged in an alternating sequence of at least one layer of each type of material. This reflector is suitable for use on the reflecting electrode of a liquid crystal video display panel fabricated on a semiconductor substrate. The use of the dielectric reflector in place of other types of reflectors increases the available reflectivity and permits a preselected color or wavelength to be preferentially reflected. The polysilicon layer of the dielectric reflector is doped with p-type or n-type impurities such as boron or phosphorus to make this layer electrically conductive.

Light is directed at a liquid crystal display with the aid of a Fresnel mirror. With the liquid crystal display upright, the mirror is placed in front of, and slightly below it, so that light from overhead is reflected at the display by the mirror's facets.

An electrical field sustained conductivity device is fabricated by successively disposing over a layer of cadmium sulfide a film of metal particles and a composite layer of metal particles in an insulating medium. When a potential is applied across the cadmium sulfide layer, an image may be stored therein by momentarily exposing the layer to electrons or light conveying that image. Such exposure introduces conductivity changes in the cadmium sulfide layer by virtue of the layers deposited on it and the conductivity changes are retained so long as the applied potential is maintained.
