A parallel Frequency Domain Optical Coherence Tomography (FD-OCT) system and - to the best of our knowledge- first in vivo tomograms obtained with such system are presented. A full tomogram of 256(x) x 512(z) pixels covering a sample region of 8 mm x 3,8 mm is recorded in only 1 ms. Since the transverse as well as the depth information is obtained in parallel, the structure is free of any motion artifacts. In order to study cross talk issues for parallel illumination the transversal resolution for a thermal light source is compared to that with an SLD.
