Patent ID: 10265873

Abstract:
A method and a gonioradiometer for the direction-dependent measurement of at least one photometric or radiometric characteristic of an optical radiation source. The emission direction of the photometric or radiometric characteristic is described using a system of planes (A, B, C), the planes of which intersect at an intersection line which passes through the radiation centroid of the radiation source, and using an emission angle (α, β, γ) which specifies the emission direction (α, β, γ) within a considered plane. A sensor or the radiation source is fastened to a multi-axis articulated robot. The robot is configured to only swivel about precisely one of its axes during a measuring process, in which measurement values relating to different emission angles (α, β, γ) within a considered plane of the system of planes (A, B, C) or to different planes at a considered emission angle (α, β, γ) are detected.
