A light beam may be separated into its orbital-angular momentum (OAM) components by a geometric optical transformation that converts each OAM component into a plane wave with a transverse phase gradient. Subsequent focusing produces a spot the latera... Read More about Efficient measurement of an optical orbital-angular-momentum spectrum comprising more than 50 states.
