    • The present invention relates to an apparatus and a method for optical coherence reflectometry, in particular for optical coherence tomography. The invention particularly relates to the route of the light field in the sample arm. The reflected light field in the sample arm is amplified before being received by a combining means, said combining means being capable of receiving the reflected light field from the sample arm as well as the second reflected light field from the reference arm. Thereby, it is possible to direct substantially all light energy in the sample arm to the combining means, and to obtain fully the utilisation of the amplification of the reflected light field since preferably only the reflected light field is amplified by the optical amplifier. This leads to an improved signal-to-noise ratio (SNR) whereby an increase of the maximal penetration depth is obtained. Thereby, the apparatus is useful for obtaining optical biopsies of transparent as well as non-transparent tissues as well as new technical fields wherein the increased SNR allows the use of the present apparatus.
    • 用于光学相干反射测量的装置和方法技术领域本发明涉及用于光学相干反射测量的装置和方法,特别是用于光学相干断层成像。 本发明特别涉及样品臂中光场的路线。 样本臂中的反射光场在被组合装置接收之前被放大,所述组合装置能够接收来自样本臂的反射光场以及来自参考臂的第二反射光场。 因此,有可能将样本臂中的基本上全部光能引导至组合装置,并且充分获得反射光场的放大的利用,因为优选地只有反射光场被光放大器放大。 这导致改善的信噪比(SNR),由此获得最大穿透深度的增加。 由此,该设备对于获得透明以及不透明组织的光学活检以及其中增加的SNR允许使用本设备的新技术领域是有用的。
