Claim 2:
3. The method according to claim 2, wherein the step of determining the orbital angular momentum of the main electromagnetic radiation beam comprises:
determining the orbital angular momentum of the main electromagnetic radiation beam based on the formula

ΔP/k−ΔR/k′∝(L1/k−L0/k′)(θ2θ1)

where θ1 is the angular position of the first detector measured on the plane orthogonal to the composite beam propagation vector containing the first detector, and θ2 is the angular position of the second detector measured on the plane orthogonal to the composite beam propagation vector containing the second detector.
