<p>The method involves utilizing an electrical digital modulation signal (5) for generating a modulated laser light. An optical signal that is rear-scattered from a fiber-optic cable (21) is supplied to analog-to-digital (A/D) converters (14, 34) and is converted into a digital response signal. The digital response signal is correlated with the modulation signal for generation of n-measuring data sets. The n-measuring data sets are delivered to an evaluation computer (40) for evaluation of an intermediate memory for generation and output of locally-solved measured values. Independent claims are also included for the following: (1) a measuring device for spatially distributed and/or distant measurement of physical values under evaluation of optical signals (2) a fiber-optic sensor cable (3) a measuring system comprising a measuring device.</p> |
