Figure 3
Probe reconstructed from NFP for the 100 µm × 100 µm slit setting, showing (a) amplitude and (b) phase in the detection plane at 0.3732 m. Scale bar: 50 µm. The focus intensity (c) and phase (d) are obtained by Fourier transformation. Scale bar: 5 mm. The corresponding propagation profile is also shown in (e) for intensity (logarithmic) and (f) for phase along the optical axis ±10 mm around the focal plane in the vertical direction. Pixels with intensity values smaller than 10−5 of the maximum value were masked out in white.
