Computational Imaging and Digital Holography Laboratory

Computational imaging and digital holography laboratory is an ICT research infrastructure with the aim to serve both research and teaching toward computational imaging, and especially toward quantitative phase imaging, which is of great interest for investigators, and particularly for biologists due to provided objective measure of morphology and dynamics of living tissue, with no sample preparation and free in variability because of the absence of contrast agents.  Complex-domain imaging is realized by digital holography, phase retrieval, and hyperspectral Fourier spectroscopy. All systems are self-build and therefore flexible according to an application.  


On the base of the infrastructure, the investigations are running on the hyperspectral phase imaging, digital holographic imaging, lensless phase retrieval imaging, and lensless imaging with an improvement of the depth of focus. In perspective, we will build adaptive wavefront shaping to go deeper into biological tissue for tomographic imaging.


  • Laboratory course “Signal processing in digital holography” (COMP.SGN.240). Laboratory work involves 2D Fourier filtering and angular spectrum wavefront propagation.
  • The practical part of the newly developed course “Computational imaging and digital holography” (COMP.SGN.330)  with laboratory works on wavefront adaptation, digital holography, compressive sensing, and image processing and enhancement.
