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…
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…
