Line-field spectral domain optical coherence tomography using a 2D camera

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 tissue of human teeth are presented.
