Abstract
Some embodiments of the invention may relate to a rangefinder, in particular for a laser scanner, laser tracker, profiler, theodolite, or a total station. In a special embodiment of the invention, the light source of the rangefinder—provided for the emission of pulsed light signals—is configured here as an optical fiber amplifier (e.g. an EDFA, i.e. erbium-doped fiber amplifier) which is optically pumped by a superluminescent diode (SLD) operated in a pulsed manner.
