The separation and detection of compound orbital angular momentum modes are the basis for achieving high-speed and high-capacity communication, but the atmospheric turbulence causes distortion of the phase fronts of vortex beams, which hinders the recognition of orbital angular momentum modes. To solve this problem, in this work, we propose and investigate a joint scheme of combining the Gerchberg-Saxton algorithm and the phase of addition and subtraction model that can achieve high recognition accuracy and a wide range of orbital angular momentum modes of compound perfect optical vortex beam under long-distance turbulence environment. At the receiving end, the Gerchberg-Saxton algorithm and phase addition and subtraction are used to compensate and modulate the incident vortex light field to obtain the pre-processed light field, and then the orbital angular momentum is detected by the coordinate transformation method. The simulation results show that: The detection range of the orbital angular momentum of the 3 optical path detection model for the vortex beam transmitting 1000m reaches -37~+37 in the vacuum environment, and the mode purity of -37~+37 can reach more than 0.3 when the turbulence intensity is Cn2=2×10-15m-2/3. The detection range of the orbital angular momentum of the vortex can be further expanded by increasing the optical path. This study provides a new method for the separation and detection of orbital angular momentum of composite vortex beams.

Detuning errors limit the accuracy of phase extraction in phase-shifting interferometry (PSI). To improve this accuracy, the systems to control the phase shifter dispositive must be highly accurate, involving high technology, exhaustive calibration, high cost, and constant maintenance. This manuscript presents a method for improving the accuracy of the phase step generated at the Fourier plane by rotating and displacing the grating in a double-aperture common-path interferometer. It is demonstrated that both the detuning errors and the phase extraction uncertainty decrease with the grating rotation angle. The experimental implementation is very simple, as it does not require any sophisticated mechanical system to improve the accuracy, no exhaustive calibration, and no additional mechanical and optical dispositive. With the present approach, the PSI method could be achieved very simply and with high accuracy by using a low-accuracy actuator. The theoretical model and experimental results are presented to demonstrate the present proposal.
