Table I.
Maximum sensitivity values and spatial coordinates of maximum sensitivity for intensity and phase measurements in the single-distance (SD) and dual-slope (DS) arrangements reported in Figs. 1–13 (LIN: linear; RHO: rhomboid; QDL: quadrilateral; IRR: irregular; RCT: rectangle; SQR: square; TPZ: trapezoid). The size of the optical inhomogeneity is 10×10×2 mm3.
