Abstract
An optical device for detecting a light beam reflected by a remote target comprises a light source, which is designed to emit the light beam in a predetermined direction at the remote target, and a primary lens, which is designed to focus the light beam reflected by the remote target into a first focal point. The optical device further comprises a relay lens system, which is arranged in such a way that the first focal point is located between the primary lens and the relay lens system and which is designed to focus the light beam reflected by the remote target and diverging starting from the first onto a second focal point. A detector unit is essentially arranged in the second focal point. A diaphragm is arranged within a cross-section, which is normal to the optical axis, of the light beam reflected by the remote target between the first focal point and the relay lens system.
