Analysis of practical fractional vortex beams at far field
Eduardo Peters, Gustavo Funes, Lluís Martínez-León +1
The subject of calculating the topological charge (TC) or vortex strength of optical vortices has generated divided opinions among scientists. This is due to the fact that proper a…
High sampling rate single-pixel digital holography system employing a DMD and phase-encoded patterns
Humberto González, Lluís Martínez-León, Fernando Soldevila +3
A single-pixel digital holography system with phase-encoded illumination using a digital micromirror device (DMD) as a spatial light modulator (SLM) is presented. The enhanced swit…
Giga-voxel multidimensional fluorescence imaging combining single-pixel detection and data fusion
Fernando Soldevila, Armin Lenz, Alberto Ghezzi +3
Time-resolved fluorescence imaging is a key tool in biomedical applications, as it allows to non-invasively obtain functional and structural information. However, the big amount of…
High-sensitivity high-speed compressive spectrometer for Raman imaging
Benneth Sturm, Fernando Soldevila, Enrique Tajahuerce +3
Compressive Raman is a recent framework that allows for large data compression of microspectroscopy during its measurement. Because of its inherent multiplexing architecture, it ha…
Single-pixel imaging with Fourier filtering: application to vision through scattering media
Yessenia Jauregui-Sánchez, Pere Clemente, Jesús Lancis +1
We present a novel approach for imaging through scattering media that combines the principles of Fourier spatial filtering and single-pixel imaging. We compare the performance of o…
Phase imaging by spatial wavefront sampling
F. Soldevila, V. Durán, P. Clemente +2
Phase imaging techniques extract the optical path-length information of a scene, whereas wavefront sensors provide the shape of an optical wavefront. Since these two applications h…
