Abstract
Abstract A radiation system consists of a compound collection/beamforming system, surrounding a source of radiation, including an elevation collector/beamformer shaped as a compound parabolic concentrator and an azimuth collector/beamformer shaped so that tangential rays emanating from the source will be collected and formed into a beam of a predetermined design, and a modulator for alternately blocking and unblocking the beam from the compound collection/beamforming system.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
A radiation system, comprising: a plurality of sources of radiation; a like plurality of compound collection/beamforming systems ech of which is disposed for receiving radiation from a corresponding one of said sources and each forms said radiation from each corresponding source into a beam of predetermined configuration radiated along an optical axis of the compound collection/beamforming system for each corresponding source, each of said compound collection/beamforming systems including an elevation collector/beamformer and an azimuth collector/beamformer, wherein each compound collection/beamforming system points in a different direction; each elevation collector/beamformer being a compound parabolic concentrator; means for modulating the beams of radiation emitted by said compound collection/beamforming systems; and an additional compound collection/beamforming system for collecting the modulated radiation from said plurality of modulated beams of radiation and forming it into a larger, more intense beam of radiation.
Claim 2
Dependent Claim
136 words
A radiation system, comprising: a plurality of sources of radiation; a like plurality of compound collection/beamforming systems ech of which is disposed for receiving radiation from a corresponding one of said sources and each forms said radiation from each corresponding source into a beam of predetermined configuration radiated along an optical axis of the compound collection/beamforming system for each corresponding source, each of said compound collection/beamforming systems including an elevation collector/beamformer and an azimuth collector/beamformer, wherein each compound collection/beamforming system points in a different direction; each elevation collector/beamformer being a compound parabolic concentrator; means for modulating the beams of radiation emitted by said compound collection/beamforming systems; and an additional compound collection/beamforming system for collecting the modulated radiation from said plurality of modulated beams of radiation and forming it into a larger, more intense beam of radiation.
Claim 3
Dependent Claim
78 words
A radiation system as defined in claim 1, wherein each azimuth collector/beamformer is configured in the form of first and second curves having a dividing line at a point where a line tangential to each source of radiation is at an angle (θ a ) with the longitudinal axis of the compound collection/beamforming system, where θ a is one half the beamwidth of the beam in azimuth, each first curve being in closer proximity to said source envelope.
Claim 4
Dependent Claim
104 words
An radiation system as defined in claim 2, wherein said first curve is determined in accordance with the formula: ##EQU4## and said second curve is determined in accordance with the formula: ##EQU5## where θ is the angle measured from the longitudinal axis to a radius of the source, ρ is the distance from the end of a radius to the point of interest, and θ d is determined from the formula: ##EQU6## where, R 2 is a scaler from the center of the source to the cusp of the azimuth collector/beamformer along the longitudinal axis, and R a is the radius of the source.
Claim 5
Dependent Claim
18 words
A radiation system as defined in claim 1, wherein each of said sources of radiation is substantially cylindrical.
Claim 6
Dependent Claim
29 words
A radiation system as defined in claim 2, wherein each of said radiation sources includes a source which emits radiation and an envelope in which said source is disposed.
Claim 7
Dependent Claim
39 words
A radiation system as defined in claim 5, wherein each of said compound collection/beamforming systems includes means for collecting substantially all of the tangential rays emanating from its respective source and forming them into said beam of predetermined configuration.
Claim 8
Dependent Claim
86 words
A radiation system as defined in claim 6, wherein each of said azimuth collector/beamformers is configured in the form of first and second curves having a dividing line at a point where a line tangential to said respective source of radiation is at an angle (θ a ) with the optical axis of the compound collection/beamforming system where θ a is one half the beamwidth of the beam in azimuth, said first curve being in closer proximity to said source envelope than said signal second curve.
Claim 9
Dependent Claim
104 words
A radiation system as defined in claim 7, wherein said first curve is determined in accordance with the formula: ##EQU7## and said second curve is determined in accordance with the formula ##EQU8## where θ is the angle measured from the longitudinal axis to a radius of the source, ρ is the distance from the end of a radius to the point of interest, and θ d is determined from the formula: ##EQU9## where, R 2 is a scaler from the center of the source to the cusp of the azimuth collector/beamformer along the longitudinal axis, and R a is the radius of the source.
Claim 10
Dependent Claim
26 words
A radiation system as defined in claim 8, wherein each of said plurality of sources of radiation being contained within a corresponding said compound collection/beamforming system.
