摘要: A real-time control system for an optical phased array is disclosed that comprises a computationally efficient algorithm calculating phase differences between plurality of beamlets and reference plane wave further generates correction signals are transmitted to modulators realign the compensate external perturbations atmospheric aberrations. The measurements based on angle complex number comprising square functions, alternately, sine cosine functions correct harmonic content measurements. Furthermore, signal measurement times modulo2π.
