| 摘要 |
A device for establishing geometric values at least from a first region (MB1) and from a second region (MB3), distanced from the first region (MB1), of a transparent or diffusive object, comprises a coherence tomograph with an object arm, a reference arm, a detector arm, and a light source (ALQ) for emitting light. The device has a first path, formed by the object arm and/or the reference arm, having a first optical path length and a second path having a second optical path length, along which the light emitted by the light source (ALQ) can propagate.
