| 摘要 |
The invention relates to an interferometric distance measuring arrangement for measuring surfaces, using at least one laser which can be tuned for generating measurement radiation modulated by a wave length ramp, an optical beam path with an optical transmitting system for emitting the measurement radiation to the surface and an optical capturing system for capturing the measurement radiation back-scattered by the surface, comprising a measuring arm and a reference arm and a radiation detector and an evaluation unit for determining the distance from a reference point of the distance measuring device to the surface. Channels are defined by at least one beamsplitter (13, 29) n >= 2 for the parallel emission of measurement radiation, respectively, one different sub area of the wave length ramp is allocated to said channels at a predetermined emission time point. |
