Line-field Spectral Domain Optical CoherenceTomography using a 2D Camera

摘要

A Line-field Spectral Domain Optical Coherence Tomography method is proposed to enable. fast B-Scan imaging This system was constructed from a combination of a conventional Spectral Domain OCT and a line field imaging system, which directs a line-shaped focus onto a specimen. An array of depth-information-encoded-spectra was collected by .a two-dimensinal CCD camera. Numeric frequency resampling was applied to rows collected from the camera, followed by Fourier transformation on each individual spectrum obtained. This lead to B-Scan images generated from a single shot event. The performances of the imaging system are discussed. Images from skin of human fingers in-vivo and osseous tissuc of human teeth are presented.
