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 (&#x3b1;, &#x3b2;, &#x3b3;) which specifies the emission direction (&#x3b1;, &#x3b2;, &#x3b3;) 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 (&#x3b1;, &#x3b2;, &#x3b3;) within a considered plane of the system of planes (A, B, C) or to different planes at a considered emission angle (&#x3b1;, &#x3b2;, &#x3b3;) are detected.

Method and gonioradiometer for the direction-dependent measurement of at least one photometric or radiometric characteristic quantity of an optical radiation source

The invention relates to a gonioradiometer for the direction-dependent measurement of at least one lighting or radiometric characteristic variable of an optical radiation source (), having: an apparatus for moving a radiation source () during a measurement operation about a first axis () and about a second axis () that is perpendicular to the first axis (); a measuring wall () exhibiting homogeneous reflection, on which the light from the radiation source () is reflected; and a locationally fixed and immovably arranged camera () having an optical unit () and a two-dimensional sensor chip (). The camera () is arranged such that it captures light reflected on the measuring wall (), wherein the reflected light is imaged by the optical unit () of the camera () onto the sensor chip () of the camera (), and wherein the sensor chip () records measurement values as the radiation source () is rotated during a measurement operation, which measurement values indicate the lighting or radiometric characteristic variable substantially on a spherical surface about the radiation centroid of the radiation source (). The invention furthermore relates to a method and a gonioradiometer for the direction-dependent measurement of at least one lighting or radiometric characteristic variable of an optical radiation source (), in which provision is made for at least two fixedly installed sensors () to be used which provide measurement values simultaneously during a measurement.
