Figure 1. Schematic diagram of how X-rays pass through object. Dashed line shows X-ray wave without object. Upper curves: cross section corresponding to X-ray phase shift. Lower curves: cross section corresponding to X-ray absorption ( Yashiro et al., 2021)

In order to improve the use, conservation, and productivity of plants, seeds, soil, and food, scientists can quickly and non-destructively analyze the internal properties and compositions of these resources using synchrotron imaging techniques utilizing a bright and tuneable technique. are the imaging setup shown in Fig. 1. Synchrotron phase ‑ contrast imaging or microtomography is very similar to SR-absorption based CT imaging; the only difference is that Fresnel fringes are produced because the detector is placed at a variable distance from the sample rather than being placed close to it as in SR-absorb tion CT base imaging. Low-density materials can also be imaged because of the technique's utilization of X-ray refraction by the sample, which draws attention to the sample's edges and internal boundaries even if the material does not absorb adequate X-rays to provide a clear abs X-ray image.
