Abstract
In certain embodiments, an OCT system sends a sample beam to a sample (e.g., an eye) along a sample path divided into multiple sample path ranges. The system sends a reference beam to a reference arm system with multiple reference arms, where each reference arm corresponds to a sample path range. Each arm has a specific dispersion level with a corresponding dispersion compensation parameter set designed to address the specific level. A detector detects reflected sample and reference beams. A computer performs the following for each sample path range: select the dispersion compensation parameter set corresponding to the reference arm of the sample path range; apply the dispersion compensation parameter set to the detector signal to yield image information; and process the image information. The computer generates an image of the sample from the image information for the sample path ranges.
