DESCRIPTION:Rainer A. Leitgeb\, Medical University of Vienna\nIt is now tw
 enty years since Optical Coherence Tomography (OCT) was introduced as prom
 ising new biomedical imaging technology. Since then it has found entrance 
 into many different fields of medicine and shows also interesting applicat
 ions in the field of biology. Several milestone developments enhanced the 
 power of this technique starting with the achievement of axial ultrahigh r
 esolution of a few micrometers\, continuing with the establishment of Four
 ier Domain (FD) OCT\, that brought a sensitivity advantage of 20dB and mor
 e as compared to previous technology\, and reaching nowadays an imaging sp
 eed record of several millions depth scans per second. An unique feature o
 f OCT is the availability of the interferometric phase\, that gives access
  to optical path length changes in the nanometer and recently also sub-nan
 ometer range. This allows for highly sensitive imaging of vascular and mic
 rovascular patterns in tissue\, such as the human retina\, or even highly 
 scattering human skin.  Also polarization contrast profits from the avail
 ability of signal phase. Nevertheless\, despite the prospering development
 s and applications of OCT there are still limitations that hinder larger a
 cceptance of OCT and its high-resolution version OCM (icroscopy) in the fi
 eld of biology.
