From: Terahertz in-line digital holography of human hepatocellular carcinoma tissue
Upsampled holograms of human hepatocellular carcinoma tissue and their reconstructions.
(a), normalised hologram. (b–c), object absorption and phase-shift distributions reconstructed from the normalised hologram. The absorption up to a = 0.22 a.u. means that up to 36.21% of the incident radiation was absorbed. (d–e), reconstructed absorption and phase-shift distributions after 200 iterations, respectively. (f), extrapolated hologram after 200 iterations. (g), the amplitude of the complex-valued field at the detector after the last iteration. (h–i), absorption and phase-shift distributions reconstructed from the extrapolated hologram.
