Wavelength Encoded Multi-beam Optical Coherence Tomography

Abstract

Optical coherence tomography (OCT) apparatuses and methods include a first electro-magnetic radiation (EMR) source providing EMR to a first optical path associated with a sample and a second optical path associated with a reference. A multi-beam generator unit (MBGU) generates first and second EMR beams having different wavelength contents. A scanning system illuminates the sample with the first and second EMR beams, at a first and second time, at a first and second location. An interference module generates interference signals based on received EMR returning from the reference and the first and second EMR beams returning from the sample. A detector generates detection signals based on received interference signals and a processor generates OCT data based on the processed detection signals. In some embodiments, three EMR beams having different wavelength contents with linearly independent vectors illuminate at least one same location of the sample.
