Web9 Aug 2024 · Fourier single-pixel imaging (FSI) is a branch of single-pixel imaging techniques. It allows any image to be reconstructed by acquiring its Fourier spectrum by using a single-pixel detector. FSI uses Fourier basis patterns for structured illumination or structured detection to acquire the Fourier spectrum of image. However, the spatial … WebSnapshot compressive imaging (SCI) uses a 2D detector to capture HD (≥3D) data in a snapshot measurement. Via novel optical designs, the 2D detector samples the HD data in a compressive manner; following this, algorithms are employed to reconstruct the desired HD data cube. SCI has been used in hyperspectral imaging, video, holography ...

Web15 Jul 2024 · In summary, we propose a compressive circular polarization snapshot spectral imager based on compressive sensing paradigm. The information is encoded in the spatial domain by a coded aperture. Two dispersion prisms, DAP and WP, are used to disperse the spectral along two orthogonal directions. Meanwhile, the combination with a QWP and a … Web1 Jul 2024 · The principle of snapshot compressive imaging (SCI) system is to encode the high-dimensional data onto a two-dimensional measurement.
