    Abstract: A drop-detection device detects a drop that escapes from a metering valve. The drop-detection device includes a light guide with first and second light-guiding elements that are arranged opposite each other at an intermediate space. A drop trajectory runs through the intermediate space such that a light beam sent out by the first light-guiding element crosses the drop trajectory and is subsequently coupled into the second light-guiding element. In addition, the drop-detection device includes a light-signal generation device that couples a pulsed light beam with a carrier frequency into the first light-guiding element. Furthermore, the drop-detection device also has a light evaluation device for evaluating the light beam coupled into the second light-guiding element to determine if a drop has been dispensed by the metering valve. A method of detecting a drop is also described.
