Figures & data
Figure 1. Polarization phase-shifting triple-interferometer. Li: Lens. MO: Microscope objective. BS: Beam splitter. PBS: Polarizing Beam splitter. Pi: Lineal polarizer filters. Mi: Mirrors. Beam cross section a = 2 mm. x0 = 2.5 mm. L1 = 100 mm (Video 1).
Figure 2. Temporal variation of the system showing the (a) four-phase shifted interferograms obtained in a single shot, its corresponding (b) wrapped and (c) unwrapped phase. By taking 1000 frames we obtain the (d) average and (e) standard deviation of each pixel of the demodulated phase.
Figure 3. Temporal variation of the unwrapped phase selecting the central pixel of Figure 2.
Figure 4. Pseudoscorpion (a) π/2- shifted interferograms captured in a single shot. (b)–(c) OPD.
Figure 5. Human red blood cells (a) π/2-shifted interferograms captured in a single shot. (b) OPD of sample of RBC. (c) OPD of single RBC. (d) Transversal section of RBC.
Figure 6. Dynamic sample (Video 2). Temporal evolution of the OPD of RBC. 5 frames per second.
Figure 7. Four plastic microparticles (a) Four π/2-shifted interferograms captured in a single shot. (b)–(c) Slope.
Figure 8. Thin film. (a) Four π/2-shifted interferograms captured in a single shot. (b)–(c) Slope.
Figure 9. Radial Mode. Spherical wavefront. (a) Four π/2-shifted interferograms captured in a single shot. (b)–(c) Radial slope.
Figure 10. Dynamic samples (Video 3). Temporal evolution of the radial slope. 2 frames per second.
