Sampling sequence and sampling points. (a) Relationship between the sampling point sequence and the Stokes parameters. (b) \(R_{d}\) corresponding to the 16 × 10 sampling points. (c) H, V, +, and − degradation polarization states corresponding to the 16 × 10 sampling points before compensation. Here, θ is the angle between the projection of the Stokes vector on the equatorial plane of the Poincaré sphere and the \(S_{1}\) axis
