断层图像记录技术

Technique for tomographic image recording
Abstract:
The invention relates to a device (10; 210; 310; 410; 510) for tomographic image recording. The device comprises a sample retainer (14), a light source (12), and a detector unit (16). The light source (12) is designed to produce a pencil beam (38), which has a beam direction (40) and which passes through a sample volume of the sample retainer (14) provided in order to accommodate a sample, and has an optical control element (30), which is able to move the pencil beam (38) passing through the sample retainer (14) transversely to the beam direction (40) while the beam direction (40) remains substantially unchanged. The detector unit (16) is designed to detect at least a portion of scattered radiation (64; 64′) escaping from a section of the pencil beam (38) within the sample volume or the sample retainer (14) in a non-spatially-resolved manner.
Abstract(Chinese):

本发明涉及一种用于断层图像记录的装置（10; 210; 310; 410; 510）。 该装置包括样品保持器（14），光源（12）和检测器单元（16）。 光源（12）被设计成产生具有光束方向（40）并且穿过样本保持器（14）的样本体积以便容纳样本的笔形笔（38），并且具有 光学控制元件（30），其能够横向于光束方向（40）移动通过样品保持器（14）的笔杆（38），同时光束方向（40）基本上保持不变。 检测器单元（16）被设计成检测在空间上从样品体积或样品保持器（14）中的笔形束（38）的一部分逸出的散射辐射（64; 64'）的至少一部分 解决方式。
