Catadioptric sensor

From Simple English Wikipedia, the free encyclopedia

A catadioptric sensor is a visual sensor that contains mirrors and lenses.[1] Video cameras are limited as to how much they can see in one view. They can lose sight of what they are recording if something causes them to move suddenly.[2] Mirrors can be carefully arranged with lenses to allow the camera lens to see a wide angle view.[3] They are often used in robotics and in astronomical telescopes. One example is a catadioptric sensor used to inspect the inside of a cylindrical pipe.[4]
