Adaptive coherence volume in full-field optical coherence tomography

Optical sectioning is instrumental for the observation of extended biological samples. It allows only a slice sample while rejecting contributions from out focus depths. The acquisition whole volume then requires an axial displacement or focus. To satisfy Nyquist sampling, this has to be equal half resolution. As lateral and resolutions are coupled by numerical aperture microscope objective in most imaging techniques, high-resolution time-consuming task, especially caused slow scanning. Here, we propose adapt resolution, extent coherence volume, filtering spectrum illumination interferometric technique. We applied our approach on full-field optical tomography show tuning 1.5 15 μ m, allowing both time amount data. finally demonstrate that method suited image large samples such as millimetric engineered tissues.
