Abstract (en)

[origin: WO2005096009A1] Disclosed is a distance meter, particularly for telescope arrays in ground-based or space-based applications for detecting surfaces. Said distance meter comprises at least one radiation source for emitting electromagnetic radiation (ES) onto a target that is to be measured, a receiver unit with a sensor (11) for receiving the radiation (S) reflected by the target and deriving distance data, and a first spectral filter component (4). According to the invention, the angular spread of reception of the reflected radiation (S) is limited by means of at least one spatial filter component (6'), especially a fiber laser as a radiation source and receiver component.
