摘要

The method involves evenly distributing the intensity of illumination over a total measuring surface. In order to achieve a high degree of uniformity, an array (1) has several LEDS (4). The LEDs are arranged at different distances from the main plane of the array and have an adjusted angle position. The irradiancy may not exceed a maximum deviation from a given average. The light cones (6) on the goal surface (3) are transferred to each other in rows. The light cones are positioned in a row and a neighboring row is positioned in the center of the distance of the light cones.
