We present several contributions of our test system to detect multiple targets with the direct time-of-flight technique. With a precise time-to-digital-converter it is possible to capture the time-of-flight of a short light pulse reflected by a target with high temporal resolution. Based on this technique we can relate the single events to its resulting distance and separate the different objects.
