Angle–sensitive pixel

An angle-sensitive pixel is like a tiny little eye that can see which way something is coming from. Imagine you're playing a game of catch with your friend and you close your eyes. Even though you can't see the ball, you can still tell where it's coming from because you can hear it, right? Well, that's sort of what angle-sensitive pixels do - they can "see" the direction things are coming from, even if they're too small to actually see objects!

These pixels work by having little sensors that can detect light coming in from different angles. The sensors are arranged in a pattern so that each one is facing a slightly different direction from the others. This way, when light comes in from a certain angle, only the sensor or sensors facing that direction will pick it up.

Scientists use angle-sensitive pixels for all sorts of things, like studying how light behaves in different environments, tracking the movements of tiny organisms, or even creating better cameras that can capture images from all angles. Pretty cool, huh?
