Abstract
The invention relates to an illuminating arrangement for illuminating an object with incident light wherein the angle of the incident light is selectable. The illuminating arrangement includes a plurality of individual light sources which can be switched on and off. The light sources are advantageously arranged in several concentric circles in different planes from which the light can be radiated along different beam axes. An illumination at different selectable angles is possible without a mechanical adjustment of the light sources or the imaging elements. The light sources can be advantageously mounted in a hemispherically-shaped carrier. The illuminating arrangement can be a component of a closed control loop and be controlled quickly and completely automatically via an image processing unit or by manual instructions of desired values via a control console.
