Reconstruction of the phase map originating from structures fabricated by etching silicon wafer, objective lens 20 × /0.45NA. (a) Input interferogram, (b) Fourier spectrum with 3 circles showing: extent of the zero-order peak (red), part of the spectrum related to carrier spatial fringes (green) and part of the spectrum selected for phase reconstruction to avoid overlapping (blue). (c–e) Comparison of phase reconstruction by TPS, HST, and FT, respectively. (f) Line profiles of part of the phase marked with blue, green and red lines on the phase maps.
