Abstract
The present disclosure relates to an apparatus and method that can be used to remotely acquire high resolution depth resolved images from a sample. The apparatus employs an adapter to an imaging device, where the adapter uses a minimum of components to produce interferometry patterns on the input facet of the imaging device. The imaging device can be a bundle endoscope terminated on a camera sensor or on several camera sensors or simply a camera sensor. In conjunction with a swept source or a broadband source, at least one camera sensor may be employed to provide optical coherence tomography (OCT) images of the sample. When the imaging device uses a bundle of optical fibers, the apparatus and method can provide OCT images tolerant to bending of the bundle.
