title: Direct measurement of Stokes orbital parameters
abstract: The method of direct measurement of the Stokes orbital parameters is based on the analogy with the standard approach to measuring the Stokes polarization parameters of structured beams. A cylindrical lens serves as a quarter-wave plate, and the action of the polarizer is associated with the action of the matrix operator of the moments of intensity P of the second order on the intensity pattern of the structured beam, taken in front of the cylindrical lens and in the double focus plane.
