该系统具有采样透镜，由干涉仪（10）发射的光聚焦在样品（1）即生物组织的焦点中。 检测器（30）检测被样品反射的光。 在反射器（12）到分束器（13）的光学距离（I）的改变期间，由检测器检测在样品的不同深度反射的光，其中在检测期间改变样品透镜的成像特性 的反射光，使得焦点位于样品的相应深度的区域中。 还包括以下独立权利要求：（1）光学相干断层摄影方法（2）校准和光学相干断层摄影系统的方法。

The invention relates to a system and a corresponding method for optical coherence tomography comprising at least one interferometer (20) for outputting, in particular spatially short or incoherent light, with which a specimen (1) is irradiated to a sample arm comprising a sample lens (41) through which emitted by the interferometer (20) light in a in the sample (1) lying focus is focused, and a preferably a plurality of which is arranged in an area detector elements comprehensive detector for detecting light emitted from the sample (1) is reflected. For a reliable recording of possible sharp images of the sample (1) is provided for the detection of different depths in the sample (1) are each reflected light to change while the imaging properties of the sample lens (41).
