Three dimensional visualisation of barley corn seed and fish tissue using Talbot Lau grating interferometer.

In this contribution we present the initial results concerning plant and animal tissue samples using a newly developed desktop Talbot-Lau grating interferometer XCT (Talbot-Lau XCT, SkyScan 1294). Plant tissue sample is an untreated and malted barley corn seed. Animal tissue sample is a fish. Talbot-Lau XCT is advantageous in non-destructive analysis field as it provides complementary information to standard absorption-based methods (AC) in the form of differential phase contrast (DPC) and dark-field images (DFI). In particular dark field imaging reveals information undisclosed by both AC and DPC imaging since dark field contrast delivers morphological information in the sub‐pixel regime depending on the local scattering power [1, 2]. As dark field images yield a high contrast and a strong signal of interfaces, the epidermal tissue of barley corn seed and gill organs of fish are visible.
