Test device for light sensors formed from radially coupled optical fibres

摘要

The arrangement consists of a reflecting flash chamber (2) with an elliptical cross-section and a first (A) and a second (B) fibre-shaped focus. A rod-shaped test light source (8) is arranged on the one side in the first focal point, and a light sensor (3) is arranged as the tested device, on the other side in the second focus. The emitted light of the test light source is focused on the light sensor. The test light source is preferably a flash lamp which is formed as an Xenon flashlight with an unlayered tube.
