Abstract

Abstract As a new type of beam pointing control technology, optical phased array has broad application prospects in the fields of laser radar and beam synthesis. However, the phase error in practical application brings great difficulties to beam detection and deflection, which must be calibrated. In this paper, a SPGD algorithm combined with Adam algorithm (ASPGD) is proposed and compared with the traditional optimization algorithm. The results show that the improved SPGD algorithm can double the convergence speed and increase the cosine similarity value by about 10%.
