摘要：The invention relates to a method and a device for determining a modificationat one object or a modification caused by an object (1.26), wherein a measurement of thelight propagation time is also possible. According to the invention, an amplitude control(1.6) regulates a transmitter light source (1.8) and a reference light source (1.9) on thebasis of a control value (1.29) in such a way that the signals from the correspondingassociated light paths have approximatively the same value at the input of a comparator(1.19). As a result, an alternative detection of extraneous light is possible. In addition, aphase regulation for measuring the light propagation time can be provided.
