Figure 3.
Effect of changing various parameters of polarized light on polarization distance. For each panel, some parameters are varied (a) object and background e-vector axis, (b) object e-vector and polarization sensitivity, (c) object and background degree of polarized light, and (d) object e-vector and degree of polarized light) and some remain constant (specified in inset text). For (d), polarization distance relative to a background with an e-vector of 30° and degree 0.5 (star) is represented by contour lines (ranging from 0 to 0.55). The small square illustrates a single stimulus that differs in polarization properties but which should be indistinguishable from the background. Unless otherwise stated, all graphs are calculated for a visual system with Sp = 10.
