Abstract
We discuss balanced time-domain full-field optical coherence tomography (FF-OCT) realized in a Mach–Zehnder configuration. The balanced detection scheme and spatial phase shifting allow single-shot acquisition and reconstruction in FF-OCT. Combined with a 2D quadrature signal-based demodulation technique applying the Riesz transform, previously illustrated for a dual-shot temporal phase shifting in FF-OCT, we demonstrate the concept for single-shot spatial phase shifting. The monitoring of dynamic processes by time-domain FF-OCT is enabled by this approach. The advantage of single-shot acquisition consists of having no failure due to phase changes over time. However, it demands an accurate registration of both spatially shifted interferograms.
