Abstract
Abstract An apparatus for measuring the scalar irradiance of a given vicinity produced by all sources over a given angular range. The apparatus includes a planar array of convex spherical surfaces, a detector oriented toward the array, and a shielding plate having holes which abut and secure the convex spherical surfaces.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
71 words
An apparatus for measuring the scalar irradiance of a given vicinity produced by all sources over a given angular range, comprising: a planar array of convex spherical surfaces; a detector oriented toward said array; shielding between said convex spherical surfaces to limit the portion of each sphere which is within the view of said detector wherein said shielding is a plate having holes which abut and secure said convex spherical surfaces.
Claim 2
Independent Claim
71 words
An apparatus for measuring the scalar irradiance of a given vicinity produced by all sources over a given angular range, comprising: a planar array of convex spherical surfaces; a detector oriented toward said array; shielding between said convex spherical surfaces to limit the portion of each sphere which is within the view of said detector wherein said shielding is a plate having holes which abut and secure said convex spherical surfaces.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 wherein said plate is coated with a specular black coating and wherein said holes are countersunk such that the edges of said holes closely fit said spherical surfaces.
