Title
Real-time correction of geometric distortion artefacts in large-volume optical coherence tomography
Author
Abstract
Large-volume optical coherence tomography (OCT) setups employ scanning mirrors and suffer from geometric distortion artefacts in which the degree of distortion is determined by the maximum angles over which the mirrors rotate. In this note, we describe a straightforward coordinate transformation scheme to correct for these artefacts in three dimensions, creating an alternative to previously reported ray-tracing schemes. We demonstrate that this recalibration procedure can be applied in real time by implementing the proposed algorithm on the graphics card of a standard computer, making it useful for topography applications. The accuracy of the proposed calibration procedure is validated over an imaging volume of 12.35×10.13×2.36 mm3 using optical moiré measurements of a highly curved object.
