LABORATORY OF DIGITAL OPTICS

Laboratory of Digital Optics (LDO) is one of the specialized laboratories at the Department of Optics, Palacký University in Olomouc, ensuring experimental activities in the framework of basic and applied optical research and supporting undergraduate and graduate studies in Digital and Instrumental Optics (DIO).

Research topics

  • Experiments on special light beams (nondiffracting and vortex beams, self-imaging effects,  polarization singularities).
  • Theoretical and experimental studies on the orbital angular momentum of light and the information content of optical vortices.
  • Optical and digital techniques of incoherent correlation holography and their implementation in fluorescence microscopy.
  • Quantitative phase imaging aided by a spatial light modulation.
  • Spiral phase contrast microscopy.
  • Three-dimensional localization and tracking of microscopic objects using a double-helix point spread function.

Experimental methods

  • Amplitude and phase modulation of light by LCOS (Liquid Crystal On Silicon) technology.
  • Experimental methods of the spatial light modulation in VIS and SWIR regions.
  • Dynamic particle manipulation in the holographic laser tweezer operating with a phase-only spatial light modulator.
  • Recording and reconstruction of fluorescent and incoherently illuminated objects by the techniques of digital holography.
  • Techniques of common-path incoherent holographic microscopy.
  • Digital holographic imaging in fluorescence microscopy.
  • Quantitative phase contrast imaging in polarization Mirau interferometry.
  • Adaptive phase modulation of light by piezoelectric mirrors.
  • Dynanic aberration compensation by methods of singular optics.
  • Phase measurement by a Shack-Hartmann sensor.
  • Diagnostics of laser beams.
