Figure 2: Acquired Fourier spectra from detectors 1 and 2 with spectrum coverage from 1 to 100% and corresponding reconstructed images.
From: Single-pixel imaging by means of Fourier spectrum acquisition
(a–d) are the density distributions of Fourier spectrum acquired from detector 1, whereas (e–h) from detector 2. (i–l) are the reconstructed images corresponding to (a–d) and (m–p) correspond to (e–h), respectively. Note that we show the absolute value of the Fourier spectrum on a logarithm scale to render them visible. The images are reconstructed by using the 2D discrete IFT algorithm. No post processing has been applied to the reconstructed images. Scale bar, 2 cm.
