Claim Text:
1. An optical coherence tomography system with space-division multiplexing, the system comprising: a long coherence light source producing light having a coherence length greater than 5 mm to provide optimal imaging depth range; a first optical device configured to split the light into reference light and sampling light; a non-sweeping reference arm receiving the reference light and producing a reference light signal; a second optical device arranged on a sample arm and configured to split the sampling light into a plurality of sampling beams and transmit the plurality of sampling beams simultaneously; an optical delay element configured to produce an optical delay between the plurality of sampling beams; a scanner arranged to receive and configured to simultaneously scan the plurality of sampling beams onto multiple different sampling locations on a surface of a sample; the second optical device operable to simultaneously receive a plurality of reflected light signals returned from the multiple sampling locations; a third optical device configured to generate a plurality of interference signals based on simultaneously receiving the plurality of reflected light signals returned from the multiple sampling locations on the surface of the sample produced by the plurality of sampling beams and the reference light signal; wherein the interference signals includes data representing digitized images of all of the multiple sampling locations simultaneously from the sample.
