Solar radiation concentration features in Linear Fresnel Reflector arrays

A technique for gathering specific information from various remote locations, especially fluorimetric information characteristic of particular materials at the various locations is disclosed herein. This technique uses a single source of light disposed at still a different, central location and an overall optical network including an arrangement of optical fibers cooperating with the light source for directing individual light beams into the different information bearing locations. The incoming light beams result in corresponding displays of light, e.g., fluorescent light, containing the information to be obtained. The optical network cooperates with these light displays at the various locations for directing outgoing light beams containing the same information as their cooperating displays from these locations to the central location. Each of these outgoing beams is applied to a detection arrangement, e.g., a fluorescence spectroscope, for retrieving the information contained thereby.

Improved lighting apparatus and method for use in decorative and in hazardous environments uses optical fibers which are illuminated from one or both ends, and which are configured to support higher order modes of light flux propagating therein to produce substantial lateral emissions of light flux through the surface of the fibers along the entire length thereof.

Lighting apparatus and method

This invention contemplates a solar to thermal energy converter comprising spaced apart light polarizing materials defining a conduit therebetween for the passage of a fluid to be heated, the polarizing materials being positioned with respect to each other, whereby the amount of solar energy transmitted through the collector and hence absorbed by the fluid is controlled Optionally and preferably, at least one of the light polarizing materials is moveable so that the axis of absorption of the polarizing materials can be adjusted with respect to each other and in reference to collector temperature so that a predetermined amount of light will be transmitted through the device, thereby controlling the temperature within the collector

Thermal solar energy collector

The present invention provides a system for the collection of electromagnetic radiation and the transmission of that radiation to a point of use. In its simplest sense, an apparatus for the collection and transmission of electromagnetic radiation comprises a cylindrical fluorescent fiber, at least one end of which is optically coupled to an optical wave guide, and means for reflecting solar radiation impinging over a relatively wide area onto said cylindrical fluorescent fiber. Preferably, a compound parabolic mirror is employed for reflecting incident solar radiation onto the optical fluorescent fiber.
