Abstract
An optoelectronic distance measuring device has at least one transmitter unit to transmit pulsed electromagnetic radiation, at least one receiver unit associated with the transmitter unit to receive the reflected radiation and an evaluation unit to determine at least the distance of objects reflecting the transmitted radiation, with a series connection of load resistors being connected after the receiver unit and a separate amplifier being associated with each load resistor to amplify the subsidiary pulse produced at the respective load resistor from an incoming, successively attenuated received pulse.
