Liao Yanna, Zhang Wei, Yin Yafang, et al. Research on and analysis of polarization controllers using rotatable retarders[J]. 2010,(1):51-53. DOI: 10.13756/j.gtxyj.2010.01.021.
The control algorithm for QHQ-typed direction-controlled polarization controllers is discussed in this paper.Simulation results show that this algorithm is ergodic.Error analysis is carried out on the correlativity between their retardation and wavelength.The result is very important for the analysis of their error compensation and improving their accuracy
