Abstract

Summary form only given. Optical Coherence Tomography (OCT) based on low-coherence interferometry has widespread applications in biomedical diagnostics as well as industrial inspections. In ordinary OCT a point-by-point scanning is required for image acquisition, which ultimately limits the image acquisition time. In the paper we present a two-dimensional (2-D) heterodyne detection technique for real-time cross-section imaging.
