High-speed gated surface profiling with closed-loop optical coherence topography.
The here presented work describes a surface profiling technique, for which the term closed-loop optical coherence topography (CLOCT) was proposed [1]. This technique is a scanning beam, servo-locked variation of low-coherence interferometry. It allows for the sub-wavelength-resolution tracking of a weakly scattering macroscopic-scale surface with the absence of significant real-time computational overhead and is thus particularly well suited to real-time surface profiling of in vivo, macroscopic biological surfaces.
