Claim:
1. An optical coherence tomographic system to image a sample, comprising: a light source for generating a beam of light, which is divided into a reference arm light and a sample arm light; an optical train in the sample arm containing a spectral disperser for dispersing the beam-of-light into a spectrum and laterally translating the spectrum along said sample in a direction parallel to the spread of the spectrum such that spatial points of said sample can be illuminated by at least two distinct portions of said spectrum by the translation of said spectrum with respect to the sample; an interferometer including a detector, for interfering back-reflected light from said spatial points with reference arm light to yield two or more partial spectrum A-scans; and a processor, for combining the two or more partial spectrum A-scans each obtained with distinct portions of said spectrum at a given spatial point into a combined A-scan.
