Moire deflectometry
So, let’s suppose you drew some lines very close to each other on a paper right? Now, let's take another paper and put it on top of the first one. Can you see how the lines of the two papers look different? They seem to merge and create some weird patterns, right?
This is kind of what happens with Moire Deflectometry! It's like putting one paper with lines on top of another paper with lines and seeing how they look different when they merge. But, in reality, it’s not papers, but two images!
Moire Deflectometry is a way to see how the surface of an object is shaped (like a ball, cylinder or anything you can imagine). It uses light to create patterns of lines (just like the lines you drew on the paper).
First, we project lines onto the surface of the object we want to measure. These lines create a pattern on the surface of the object, kind of like a tattoo. After that, we take a picture of the pattern with a special camera.
Then, we do it again, but this time we change the angle of the lines (by turning a knob, for example). This creates a second pattern on the surface.
Now, we have two images, each with a different pattern! We use a computer to merge them, just like putting the two papers on top of each other. When the patterns merge, they create a new pattern called MOIRE that shows us how the object's surface is shaped.
Cool, right? With Moire Deflectometry, we can measure things like the size of a ball, the shape of a car or a plane wing, and even the surface of a tiny microchip!
