Optical coherence topography based on a two-dimensional smart detector array

A low-coherence reflectometer based on a conventional Michelson interferometer and a novel silicon detector chip with a two-dimensional array of pixels that allows parallel heterodyne detection is presented. We demonstrate acquisition of three-dimensional images with more than 100,000 voxels per scan at a sensitivity of $-58 \mathrm{dB}$ and a rate of 6 Hz.
