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.
