“…A simple qualitative OAM identification is given by the diffraction at a triangular aperture [31]. Other methods include the rotational frequency shift [32,33], dove prism interferometers [34,35], a circular array of coherent receivers [36], application of a nonlinear interferometer [37], and sorters transforming the OAM to transverse momentum with specific refractive elements [38][39][40][41] that provide robust and efficient sorting of OAM states in multimode fields even at the single photon level [42]. For micromanipulation of particles, however, not only the detection of single OAM states is of interest, but also the distribution of the OAM, the OAM density.…”

We present the measurement of the orbital angular momentum (OAM) density of Bessel beams and superpositions thereof by projection into a Laguerre-Gaussian basis. This projection is performed by an all-optical inner product measurement performed by correlation filters, from which the optical field can be retrieved in amplitude and phase. The derived OAM densities are compared to those obtained from previously stated azimuthal decomposition yielding consistent results.

“…A number of techniques to detect the topological charge of optical vortices have been reported [12][13][14][15][16] . Approaches that utilize amplitude diffractive optical elements, including composite fork shaped grating [17][18][19] and triangular slit [20,21] , are demonstrated.…”

A phase-diffractive optical element is designed to measure the topological charge of optical vortices. We use the scalar diffraction theory to calculate the far-field diffraction patterns. The simulation results show that almost all of the power of the incident beams is diffracted to the same diffraction order, and this approach is also effective for multi-ring optical vortices. We upload this phase-diffractive optical element on the liquid crystal spatial light modulator to do the experiment. The observed far-field diffraction patterns fit well with the simulation results.
