Talbot-Lau interferometry

Talbot-Lau interferometry is a technique that uses a series of three gratings to observe wave-like behavior of particles, such as electrons or molecules, even when they are not perfectly coherent. The first grating creates multiple wavefronts, the second causes these waves to overlap and form an interference pattern, and the third helps detect this pattern. This method allows scientists to study small particles and their quantum properties with high sensitivity, providing insight into their wave nature and interactions, and enabling applications in material analysis, imaging, and fundamental physics research.
