摘要： The invention relates to a device (1) for measuring a periodic signal, comprising a light source (3) for generating an optical input signal directed at an object being measured from an electrical input signal (8) generated by a driver device (5) on the basis of a first clock pulse (7), an optical receiver (9) for detecting and converting the signal received by the object being measured, said signal corresponding to the optical input signal altered in terms of phase and amplitude, into an electrical measuring signal (12), a central control and measuring device (10), which is designed to generate the first clock pulse (7) for the driver device (5) and to receive and process the electrical measurement signal (12, 13), and a voltage supply apparatus for supplying the driver device (5), wherein said central control and measuring device (10) is designed to generate a second clock pulse (19) for the voltage supply apparatus and filter the electrical measurement signal (12, 13) on the basis of the first and/or second clock pulse (7, 19), wherein the frequency of the second clock pulse (19) is an even multiple of the frequency of the first clock pulse (7).
