If the departure of relative phase from its target value was followed by phase wandering, the post-transition mean was assigned a value of ±180° the target.
Although a departure from linear phase variation with a small amount of defocus is not readily evident in Fig. 2(b), this effect is clearly observed after a line with slope 4 πn/ λ is subtracted from the data.
