Paper Abstract

In the paper, the selected results of the using a CCD camera to record effects of luminescence occurring in a multi-LED matrix are given. A structure of the measuring system and parameters of applied elements are presented. The images get from the CCD camera are compared for different configurations of shining and not-shining LEDs creating a given matrix. An analysis of possible interaction between optical signals emitted by adjacent diodes has been made. The studies are focused on the important metrological problems resulting from technical parameters of the CCD camera, elements applied to signals conditioning and existing conditions of the measurement. Especially, the time limitations in recording the luminescence effects, when to use the CCD camera for their recording, are considered.
