Abstract:
1. An extended depth Fourier Domain Optical Coherence Tomography (FDOCT) imaging system, the system comprising: an optical source having a bandwidth; an optical detection system having a first mode of operation configured to sample a first plurality of spectral elements within the bandwidth of the optical source at substantially equal optical frequency intervals, wherein the optical frequency interval is less than or equal to about 10.7 GHz and wherein a number of sampled elements is greater than or equal to 1024; and a reference arm, a sample arm and an optical combiner, the optical combiner being configured to couple the reference arm and the sample arm to the optical detection system, wherein a transform is applied to a set of the sampled first plurality of spectral elements to derive spatial domain data; and wherein a reference arm path length associated with the reference arm and a sample arm path length associated with the sample arm are configured to set a position of an image of a structure of a sample within a spatial domain image window.
