Parallel Fourier domain optical coherence tomography: measurement of the human eye in vivo

We present an Optical coherence tomography (OCT) system which records full tomograms of in vivo eye structure in parallel. A full tomogram of 256(x) x 512(z) pixels covering a sample region of 6.7mm x 3,8mm is recorded in only 1ms. A standard Superluminescent diode (SLD) is used which results a depth resolution of 17 mm. Since neither depth nor transverse scanning is necessary, the system allows capturing full tomograms with high acquisition speed and reduced motion artifacts. To the best of our knowledge we present the first in vivo tomogram obtained with full parallel FD OCT system. 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.
