Abstract
According to the invention, a light signal is emitted to one or several targets in order to derive geodetic distance data therefrom. Apparatus components such as transmitters (″) and receivers (″) are modeled along with the targets (and) as a linear, time-invariant system which is excited by means of a signal s(t) and the system response y(t) of which is recorded. Unlike in delay meters or phase meters, the distance data is derived from both the delay and the signal form of the system response.
