It is now twenty years since Optical Coherence Tomography (OCT) was introduced as promising new biomedical imaging technology. Since then it has found entrance into many different fields of medicine and shows also interesting applications in the field of biology. Several milestone developments enhanced the power of this technique starting with the achievement of axial ultrahigh resolution of a few micrometers, continuing with the establishment of Fourier Domain (FD) OCT, that brought a sensitivity advantage of 20dB and more as compared to previous technology, and reaching nowadays an imaging speed record of several millions depth scans per second. An unique feature of OCT is the availability of the interferometric phase, that gives access to optical path length changes in the nanometer and recently also sub-nanometer range. This allows for highly sensitive imaging of vascular and microvascular patterns in tissue, such as the human retina, or even highly scattering human skin. Also polarization contrast profits from the availability of signal phase. Nevertheless, despite the prospering developments and applications of OCT there are still limitations that hinder larger acceptance of OCT and its high-resolution version OCM (icroscopy) in the field of biology.
