    • openAccess   Compressive imaging in scattering media 

      Durán, Vicente; Soldevila, Fernando; Irles, Esther; Clemente Pesudo, Pedro Javier; Tajahuerce, Enrique; Andrés, Pedro; Lancis, Jesús Optical Society of America (2015)
      One challenge that has long held the attention of scientists is that of clearly seeing objects hidden by turbid media, as smoke, fog or biological tissue, which has major implications in fields such as remote sensing or ...

    • openAccess   Computational imaging with a balanced detector 

      Soldevila, Fernando; Clemente Pesudo, Pedro Javier; Tajahuerce, Enrique; Uribe-Patarroyo, N.; Andrés, Pedro; Lancis, Jesús Nature Publishing (2016-06-29)
      Single-pixel cameras allow to obtain images in a wide range of challenging scenarios, including broad regions of the electromagnetic spectrum and through scattering media. However, there still exist several drawbacks that ...

    • openAccess   Fast compressive Raman bio-imaging via matrix completion 

      Soldevila, Fernando; Dong, Jonathan; Tajahuerce, Enrique; Gigan, Sylvain; Barbosa de Aguiar, Hilton Optical Society of America (2019)
      Raman microscopy is a powerful method combining non-invasiveness with no special sample preparation. Because of this remarkable simplicity, it has been widely exploited in many fields, ranging from life and materials ...

    • openAccess   High sampling rate single-pixel digital holography system employing a DMD and phase-encoded patterns 

      González, Humberto; Martínez-León, Lluís; Soldevila, Fernando; Araiza Esquivel, María A.; Lancis, Jesús; Tajahuerce, Enrique Optical Society of America (2018)
      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 switching rate of DMDs, far exceeding the ...

    • openAccess   High-resolution adaptive imaging with a single photodiode 

      Soldevila, Fernando; Salvador Balaguer, Eva; Clemente Pesudo, Pedro Javier; Tajahuerce, Enrique; Lancis, Jesús Nature Publishing Group (2015-09)
      During the past few years, the emergence of spatial light modulators operating at the tens of kHz has enabled new imaging modalities based on single-pixel photodetectors. The nature of single-pixel imaging enforces a ...

    • closedAccess   High-Sensitivity High-Speed Compressive Spectrometer for Raman Imaging 

      Sturm, Benneth; Soldevila, Fernando; Tajahuerce, Enrique; Gigan, Sylvain; Rigneault, Herve; de Aguiar, Hilton B. American Chemical Society (2019-04-25)
      Compressive Raman is a recent framework that allows for large data compression of microspectroscopy during its measurement. Because of its inherent multiplexing architecture, it has shown imaging speeds considerably higher ...

    • openAccess   Image transmission through dynamic scattering media by single-pixel photodetection 

      Tajahuerce, Enrique; Durán, Vicente; Clemente Pesudo, Pedro Javier; Irles, Esther; Soldevila, Fernando; Andrés, Pedro; Lancis, Jesús Optical Society of America (2014)
      Smart control of light propagation through highly scattering media is a much desired goal with major technological implications. Since interaction of light with highly scattering media results in partial or complete depletion ...

    • closedAccess   Imaging through scattering media with single-pixel detection 

      Irles, Esther; Soldevila, Fernando; Jauregui-Sánchez, Y.; Clemente, Pere; Durán, Vicente; Tajahuerce, Enrique; Andrés, Pedro; Artal, Pablo; Lancis, Jesús SPIE (2017)
      We describe a method to image objects through scattering media based on single-pixel detection and microstructured illumination. Spatial light modulators are used to project a set of microstructured light patterns onto the ...

    • openAccess   Phase imaging by spatial wavefront sampling 

      Soldevila, Fernando; Durán, Vicente; Clemente Pesudo, Pedro Javier; Lancis, Jesús; Tajahuerce, Enrique Optical Society of America (2018)
      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 have different technical requirements, ...

    • closedAccess   Single-pixel polarimetric imaging spectrometer by compressive sensing 

      Soldevila, Fernando; Irles, Esther; Durán, Vicente; Clemente Pesudo, Pedro Javier; Fernández Alonso, Mercedes; Tajahuerce, Enrique; Lancis, Jesús Springer (2013-12)
      We present an optical system that performs polarimetric spectral imaging with a detector with no spatial resolution. This fact is possible by applying the theory of compressive sampling to the data acquired by a sensor ...
