ELECTRO-OPTICAL DISTANCE MEASURING DEVICE

摘要

An electro-optical distance measuring device includes a laser driver for a laser diode for emitting laser light pulses. The laser driver has a laser diode voltage supply for providing a voltage below a laser threshold voltage of the laser diode, an inductive component in a supply path of the laser diode, and an electronic switching element. The electronic switching element is arranged in an interacting manner such that a current flow through the inductive component can be generated in a first switching position of the switching element and the current flow can be conducted through the laser diode in a second switching position of the switching element. One of the laser light pulses can be emitted as the result of a switch from the first switching position to the second switching position, and laser light cannot be emitted in the static first switching position or the static second switching position.
