    2. Professor Andrzej Kowalczyk Celebration Gala

      Professor Andrzej Kowalczyk Celebration Gala
      On September 15 th 2018, the Institute of Physics at Nicolaus Copernicus University in Toruń, Poland, held a special event to celebrate the academic achievements of Professor Andrzej Kowalczyk, on the occasion of his retirement. Professor Kowalczyk has been a great mentor, teacher, scholar and ambassador of science over his lengthy career. At the conclusion of his PhD thesis viva voce on spectroscopy, the great Jabłoński, the grandfather of fluorescence ...

    3. Method and apparatus for imaging of semi-transparent matter

      Method and apparatus for imaging of semi-transparent matter
      The invention relates to a method and apparatus for measuring the spatial and velocity distribution of scattering structures of a sample in semi-transparent matter. The acquired spectral data I(k, t) are transformed in two steps to image data I(z, v). A Doppler shift is imposed on the light to a separate real and mirror images in the v space to suppress the complex ambiguity artifact.

    4. Differentiation of morphotic elements in human blood using optical coherence tomography and a microfluidic setup

      Differentiation of morphotic elements in human blood using optical coherence tomography and a microfluidic setup
      We demonstrate a novel optical method for the detection and differentiation between erythrocytes and leukocytes that uses amplitude and phase information provided by optical coherence tomography (OCT). Biological cells can introduce significant phase modulation with substantial scattering anisotropy and dominant forward-scattered light. Such physical properties may favor the use of a trans-illumination imaging technique. However, an epi-illumination mode may be more practical and robust in many applications. This study describes ...

    5. Apparatus for optical frequency domain tomography with adjusting system

      Apparatus for optical frequency domain tomography with adjusting system
      In an apparatus for imaging of objects by applying optical frequency domain tomography and provided with an adjusting system for setting a relative position of photosensitive elements (174) and a spectrum image (273), the adjusting system is an automatically controlled device causing a relative displacement of at least one photosensitive element (174) of the detection device (173) of the spectrum and the spectrum image (273) between each other. The adjusting ...

    6. Applicability of Optical Coherence Tomography at 1.55 μm to the Examination of Oil Paintings

      Applicability of Optical Coherence Tomography at 1.55 μm to the Examination of Oil Paintings
      With 47 samples of commercially available oil paints, the applicability of Optical coherence tomography to noninvasive tomography of paint layers was examined. Two different instruments, utilizing near-infrared light with central wavelength of 823nm and, for the first time, 1.55 μm, were used to obtain cross-sectional images. Example tomograms are given; a ray tracing correction of images is also discussed. The tests revealed that applicability of OCT is limited to ...

    7. Simultaneous analysis of flow velocity and spectroscopic properties of scattering media with the use of joint Spectral and Time domain OCT

      In this paper we describe how to simultaneously retrieve spectroscopic and flow velocity information of scattering media such as biological tissues with the use of Optical Coherence Tomography (OCT). The main problem which must be overcome during spectral information recovery is random speckle noise. It cannot be effectively removed if the medium is stationary. However, if during the measurement time there is a continuous change of locations of scattering particles ...
