<\/p>\n
Maciej Wojtkowski to jeden z czo\u0142owych polskich ekspert\u00f3w w obszarze biofotoniki. Niedawno otrzyma\u0142 presti\u017cowy grant “Mi\u0119dzynarodowa Agenda Badawcza” Fundacji Nauki Polskiej na stworzenie nowego instytutu badawczego. W 2012 roku r\u00f3wnie\u017c FNP przyzna\u0142a mu Nagrod\u0119 Fundacji, nazywan\u0105 cz\u0119sto “Polskim Noblem”.<\/p>\n
<\/p>\n
Wierzymy, \u017ce spotkanie z Maciejem Wojtskowskim b\u0119dzie unikaln\u0105 okazj\u0105 poznania jego projekt\u00f3w badawczych i zadania pyta\u0144 o jego \u015bcie\u017ck\u0119 kariery.<\/p>\n

[English version]<\/p>\n
We would like to invite for meeting with prof. Maciej Wojtkowski who prepared for us presentation \u201cCan the tissue be a lens?\u201d. Maciej Wojtkowski will present one of his ongoing research projects which he coordinate as Team Leader in Physical Optics and Biophotonics research group in Institute of Physical Chemistry PAS.<\/p>\n
<\/p>\n
Maciej Wojtkowski is one of the leading experts in Poland in field of biophotonics. Recently he received prestigious grant \u201cInternational Research Agenda\u201d from Foundation for Polish Science to establish new research institute. In 2012 the same Foundation granted him FNP Prize which is often called \u201cPolish Nobel Prize\u201d.<\/p>\n
<\/p>\n
We believe that meeting with Maciej Wojtkowski will be an unique opportunity to discover his research projects and ask him question regarding his career path.<\/p>\n
<\/p>\n
The meeting is scheduled for 3rd of April 2019, at 17:30 in room B2.38 in Faculty of Physics of University of Warsaw. After the official part of the meeting we would like you to join in one of the nearby pub to continue discussion in less formal atmosphere.<\/p>\n

Abstract:<\/p>\n
One of the most appealing and still unsolved problems in biological and medical imaging is the possibility of non-invasive visualization of tissue in vivo with an accuracy of microscopic examination. It is especially emphasized nowadays in era of novel microscopic techniques, which have ability for optical depth sectioning without need of processing samples.<\/p>\n
<\/p>\n
The main physical limitation of the in vivo microscopic imaging is associated with light scattering introduced by irregular and often discontinuous distribution of refractive index. Scattering of light limits the number of ballistic photons delivered to and received from the sample. As a consequence, the contrast of reconstructed images is compromised dramatically by increased noise. Another side effects of uneven distribution of the refractive index are significant deformations of images. Additionally, in case of coherent illumination with laser light there is a disturbing presence of so-called speckles \u2013 strong fluctuations of intensity caused by interference of mixed transverse modes of the laser beam. Speckle noise also degrades system resolution and reduces image quality. Adding all of these effects results in severe loss of imaging information.<\/p>\n
<\/p>\n
In our work we try to solve these fundamental physical limitations by developing new optical coherence imaging techniques, which utilize spatio-temporally partially coherent light with access to intensity and phase of detected radiation. In our research activity we focus on developing new optical methods that enable to image biological objects in vivo and in minimally invasive way. We went long way covering significant spectrum of various sizes of objects \u2013 from organ-size scale up to internal structure of a single cell.<\/p>\n","protected":false},"excerpt":{"rendered":"
