Claim Text:
1. An optical coherence tomography (OCT) system for imaging a sample, said system comprising: a light source for generating a beam of radiation; a beam divider for separating the beam of radiation into a sample arm and a reference arm; optics for scanning the beam in the sample arm over a set of transverse locations on the sample; a detector for measuring light returned from both the sample arm and the reference arm at a fundamental acquisition rate and generating signals in response thereto; and a processor for processing the signals and generating images of the sample based on the processed signals, said OCT system capable of having a first mode and a second mode, wherein the fundamental acquisition rate of the detector is the same in the two modes, but wherein the generated signals in the second mode are digitally combined prior to signal processing to create a data set with an effective acquisition rate less than the fundamental acquisition rate.
