Moiré Phase Tracking
So, imagine you have two pieces of paper with little lines on them. When you put them on top of each other, the lines look like they're moving or changing. That's because the lines on each paper make a pattern that kind of fights with each other.
Moiré phase tracking is a way scientists use this idea to keep things in place while they move. They use two grids or patterns, one on the thing they want to track and one on a stationary surface. By watching how the lines move and change when the two grids overlap, they can tell how the object is moving.
Think of it like having two coloring books with pictures of animals. When you put one on top of the other, sometimes the lines of the animals line up and make them look bigger or smaller or like they're moving. Scientists use this same idea to keep track of things that are moving or changing.
