Measurement results of linearly polarized artificial light (Stokes \(Q/I=1\) and \(U/I=1\)). The range of the x-axis corresponds to one rotation of the waveplate, which includes 16 image acquisitions represented by vertical stripes. Each image has 512 rows, and the average light intensities detected by each row are plotted at the row clock corresponding to their readout timings. Each segment of the curves (one of them is marked by an orange circle) is comprised of 511 data points (row 1 contains dummy data). The measurement results for both the Stokes Q/I and U/I inputs show sinusoidal variations. Each line is similar to a single sinusoidal curve; however, the measurement results of 16 contiguous rotations are overplotted
