We report a new simple optical system for the highly efficient measurement of the Orbital Angular Momentum States of Light. It uses an image reformatter to map each input state onto a different lateral position in the output aperture. This, near perfect, separation of states potentially makes available the high information capacity of OAM in both classical and quantum applications.
