Abstract: A filtering system is disclosed for receiving and bandpass filtering free space optical signals. The filtering system includes a plurality of optical fibers for accepting an optical signal. The fibers are implanted in an embedding material, having an index of refraction which is less than the optical fiber, for collimating the optical signal. The signal is further passed through a narrow, bandpass filter before detection by a photodetector device. In an alternative embodiment, the optical fibers are enclosed in a cladding, having a surface roughness at the interface of the cladding and the fiber, for enhancing the collimation of the optical signal.

Abstract: A reflector for coupling light from a light source into an optical waveguide includes input and output ends, a central axis and a reflecting surface disposed around the central axis. A light source, such as an arc lamp, is positioned on the central axis at the input end of the reflector. An input end of an optical waveguide is positioned on the central axis at the output end of the reflector. The reflecting surface has a first section adjacent to the input end with a first curvature that is concave toward the central axis, a second section adjacent to the output end with a second curvature that is concave away from the central axis, and an inflection section between the first and second sections. The first and second curvatures are selected to reflect light through the output end of the reflector within a prescribed range of angles that corresponds to the acceptance angle of the optical waveguide.

Abstract: A method of prolonging the life of thin film dichroic coated lamp components and of employing inexpensive components has been discovered. This method is the use of a hydrogen getter located in the outer jacket of the lamp, adjacent to the dichroic coating. The getter is preferably located and aligned so as to reach an optimum operating temperature.

Abstract: An arc discharge lamp having a sealed envelope including a major body portion and at least one minor transverse end portion. A non-specular light diffusing surface is axially located between the minor transverse end portion and one of the lamp electrodes. A phosphor layer within the sealed envelope subtends the major body portion of the envelope. The surface brightness of the phosphor layer as viewed through the minor transverse end portion of the envelope is greater than the intensity of the external surface brightness of the phosphor layer on the major body portion of the envelope during operation of the lamp. A lamp array for use as an element in a picture display is also disclosed including a plurality of sealed envelopes. In the case of a color presentation of information, one picture element is composed of three sealed envelopes phosphor coated with the primary colors red, green and blue.

Abstract: A metal halide arc discharge lamp having a gaseous fill within the outer envelope and means for suppressing convection currents within such fill; and methods of operating and constructing such lamps. A light-transmissive sleeve or enclosure surrounding the arc tube laterally and about at least one end thereof is so shaped and mounted with respect to the arc tube as to insure that the Rayleigh Number, a quantitative measure of convective flow, in the atmosphere laterally surrounding the arc tube will be less than 5.times.10.sup.4 during operation of the lamp whereby excessive convective heat loss in such lamp will be effectively suppressed.

Abstract: An electrically-activated photoflash lamp unit including a linear array of lamps positioned within a housing which pivots about the unit's coupling means. The coupling means includes an elongated body member having a connector tab at one end thereof for plugging within a camera's socket. Sequential activation of the lamps is provided by flash-activating pulses from the camera's power source which pass up through the elongated body member and pivot location of the housing to each lamp.
