Multi-channel optical coherence tomography

摘要

An optical coherence tomography apparatus includes a multi-beam configuration unit comprising at least a first optical path having a first numerical aperture and a second optical path having a second numerical aperture. The multi-beam configuration unit orients the second optical path in a selected orientation in space relative to the first optical path. A scan system illuminates a sample with non-polarized light received from the multi-beam configuration unit and directs light returning from the sample to the first optical path and the second optical path. The multi-beam configuration unit directs light returning from the sample, along the first optical path and the second optical path, to an optical pathway leading to a processing system. The processing system performs optical coherence tomography motion analysis based on interference between light returning from the sample and a first reference signal.
