Talbot Effect in X-Ray Imaging

X-ray imaging has seen many applications in e.g. the areas of medical imaging and industrial inspection. A common design of X-ray imaging devices is based on the Talbot effect – a diffractive effect, where a periodic structure, like a grating, will produce the exact image of the structure at a certain distance behind it.

Being a software platform based on fast physical optics, VirtualLab Fusion offers suitable solvers to propagate light through such devices, including all diffractive effects. For a short demonstration of VirtualLab Fusion’s capabilities in this area, check out the examples below:

Single-Grating Interferometer for X-Ray Imaging

Cross-pattern phase grating shown in optical design software
The configuration of an single grating interferometer for X-ray imaging is shown, starting from the point source as input field, over the phase grating with different patterns to the self-image of the cross-pattern phase grating.

Three types of gratings (modeled by phase-only transmissions) are employed in a single-grating interferometer for X-rays, and the self-images of the selected gratings are examined.

Modeling of the Talbot Effect

We demonstrate the modeling of the Talbot effect, a well-known near-field diffraction effect of periodic structures such as gratings.
