Alright kiddo, so do you know what waves are? Picture when you splash around in a pool and you see the ripples spreading out from where you splashed. That's a wave.
Now imagine you're trying to take a picture of something, but it's not in focus. That means the light waves coming from the object are all over the place and not organized, like the ripples in the pool. This makes the picture blurry and hard to see.
Wavefront coding is a special camera technique that helps fix this problem. It uses a special lens that makes the light waves coming from the object look more organized, like neat rows of ripples in the pool. This helps the camera better focus on the object and take a clearer picture.
So basically, wavefront coding makes it easier to take good pictures even if things aren't in focus. Pretty cool, right?
