Abstract
A high speed endoscopic optical coherence tomography (OCT) system is developed to enable in vivo OCT imaging of internal organ systems. The endoscopic system consists of a self-phase-modulated Forsterite laser coupled into a fiber optic Michelson interferometer. The laser is set to produce an output power of 30 mW with a Gaussian FWHM spectral bandwidth of 75 nm centered at 1280. The fiber and beam directing optics are rotated so that the OCT beams scans an angular, radar-like pattern to image cross sectionally through the structure into which it is inserted. The rapidly scanning delay line enables the acquisition of 2000 axial scans per second for a 500 pixel transverse image.
