High-resolution single-pixel imaging in real time with iterative or deep learning-based reconstruction enhancement
Anna Pastuszczak, Rafał Stojek, Piotr Wróbel +3
We introduce a compressive single-pixel imaging (SPI) framework for high-resolution image capture in fractions of a second. This framework combines a dedicated sampling strategy wi…
Single pixel imaging at high pixel resolutions
Rafał Stojek, Anna Pastuszczak, Piotr Wróbel +1
The usually reported pixel resolution of single pixel imaging (SPI) varies between and pixels falling far below imaging standards with classical met…
Differential real-time single-pixel imaging with Fourier domain regularization -- applications to VIS-IR imaging and polarization imaging
Anna Pastuszczak, Rafał Stojek, Piotr Wróbel +1
The speed and quality of single-pixel imaging (SPI) are fundamentally limited by image modulation frequency and by the levels of optical noise and compression noise. In an approach…
Far-field intensity signature of sub-wavelength microscopic objects
Maria Bancerek, Krzysztof M. Czajkowski, Rafal Kotynski
Information about microscopic objects with features smaller than the diffraction limit is almost entirely lost in a far-field diffraction image but could be partly recovered with d…
Single-pixel imaging with sampling distributed over simplex vertices
Krzysztof M. Czajkowski, Anna Pastuszczak, Rafal Kotynski
We propose a method of reduction of experimental noise in single-pixel imaging by expressing the subsets of sampling patterns as linear combinations of vertices of a multidimension…
Real-time single-pixel video imaging with Fourier domain regularization
Krzysztof M. Czajkowski, Anna Pastuszczak, Rafal Kotynski
We present a closed-form image reconstruction method for single pixel imaging based on the generalized inverse of the measurement matrix. Its numerical cost scales linearly with th…
Single-pixel imaging with Morlet wavelet correlated random patterns
Krzysztof M. Czajkowski, Anna Pastuszczak, Rafał Kotyński
Single-pixel imaging is an indirect imaging technique which utilizes simplified optical hardware and advanced computational methods. It offers novel solutions for hyper-spectral im…
Efficient adaptation of complex-valued noiselet sensing matrices for compressed single-pixel imaging
Anna Pastuszczak, Bartłomiej Szczygieł, Michał Mikołajczyk +1
Minimal mutual coherence of discrete noiselets and Haar wavelets makes this pair of bases an essential choice for the measurement and compression matrices in compressed-sensing-bas…
Compressive phase-only filtering at extreme compression rates
David Pastor-Calle, Anna Pastuszczak, Michal Mikolajczyk +1
We introduce an efficient method for the reconstruction of the correlation between a compressively measured image and a phase-only filter. The proposed method is based on two prope…
Multilayer metamaterial absorbers inspired by perfectly matched layers
Anna Pastuszczak, Marcin Stolarek, Tomasz J. Antosiewicz +1
We derive periodic multilayer absorbers with effective uniaxial properties similar to perfectly matched layers (PML). This approximate representation of PML is based on the effecti…
Optimised low-loss multilayers for imaging with sub-wavelength resolution in the visible wavelength range
Anna Pastuszczak, Rafal Kotynski
We optimise the effective skin-depth and resolution of Ag-TiO2, Ag-SrTiO3, and Ag-GaP multilayers for imaging with sub-wavelength resolution. In terms of transmission and resolutio…
Two-dimensional point spread matrix of layered metal-dielectric imaging elements
Rafal Kotynski, Tomasz Antosiewicz, Karol Krol +1
We describe the change of the spatial distribution of the state of polarisation occurring during two-dimensional imaging through a multilayer and in particular through a layered me…
Fourier Optics approach to imaging with sub-wavelength resolution through metal-dielectric multilayers
Rafal Kotynski
Metal-dielectric layered stacks for imaging with sub-wavelength resolution are regarded as linear isoplanatic systems - a concept popular in Fourier Optics and in scalar diffractio…
Sub-wavelength diffraction-free imaging with low-loss metal-dielectric multilayers
