Abstract
The invention relates to a range measurement apparatus, in particular a single beam pulsed laser range finder, comprising a light transmitter, a light receiver, an optical attenuator disposed in the transmission or reception branch and a time measuring unit for determining the light transit time between the transmission and the receipt of a light signal. The light transmitter is formed as a unitary and compact module into which a laser diode, connection elements for the laser diodes, an apparatus for coupling out the reference pulse, and also a fiber plug connector for the coupling of the transmitted light into a light conducting fiber are integrated. The light receiver is likewise formed as a unitary and compact module into which a photodiode, connection elements for the photodiode, an apparatus for coupling in the reference pulse and also a fiber plug connector for the coupling in of the received light which takes place via a light conducting fiber are integrated.
