    摘要: The invention relates to an electro-optical distance measuring method wherein frequency-modulated optical radiation is emitted onto at least one target to be measured. Once the radiation back-scattered to the target is received, the chirp of radiation is modeled by means of a phase function Φ(t) having parameters cj, thereby making description of the deviation of the chirp from the linear profile possible. The parameters used for description are at least partially determined from measurements or are coestimated during numerical signal processing.

    摘要: In a distance-measuring method comprising a distance-measuring apparatus having at least one frequency-modulatable laser source for producing chirped laser radiation. The laser radiation has radiation components with opposite chirp as time dependency of the modulated wavelengths, the simultaneous oppositeness of the frequency curve being realized via an optical delay path (3) for one of the two radiation components. The radiation produced is passed in a measuring interferometer (5) to a target (6) and parallel via a local Oscillator. After reception of the laser radiation scattered back from the target (6) and passed via the local oscillator path, the laser radiation received is converted into signals and the distance to the at least one target (6) is determined from the signals on the basis of interferometric mixing.

    摘要: The invention relates to a method for interferometric absolute distance measuring by a frequency modulation electromagnetic radiation on at least one measurable target and for subsequently receiving a retransmitted radiation with a heterodyne mixture, wherein the radiation is guided in a parallel direction via a reference interferometric length. In such a way, a first digitized interferogram of the radiation retransmitted by the target and a second digitised interferogram of the radiation guided on the reference length are obtainable at a reception. According to phase progression data of the second interferogram, a virtual interferogram or a phase progression thereof is synthesized and the distance determination is carried out by comparing the progression face data of the first interferogram with the progression face data of the virtual interferogram.
