    Dynamic mode switching for multi-mode ophthalmic optical coherence tomography

    Techniques and apparatus for selectively producing half-depth and full-depth OCT images, based on a swept-source OCT interference signal. An example method comprises selecting from a first sampling rate and a second sampling rate, the second sampling rate being twice the first sampling rate, and sampling the swept-source Optical Coherence Tomography (OCT) interference signal at the selected sampling rate, using a k-clock signal having a frequency range corresponding to the first sampling rate, to produce a sampled OCT interference signal. The method further comprises processing the sampled OCT interference signal to obtain an OCT image, such that the resulting OCT image ...
