Nuller
From Wikipedia, the free encyclopedia
A nuller is a tool used to block out a strong source so that fainter nearby signals can be observed. An example of a nuller is being employed on the Keck Interferometer. This causes the light from a star to destructively interfere, effectively cancelling out the star's image. The faint light from an orbiting ring of dust can then be detected. This project is part of a scientific effort to detect and observe nearby planets.
