Abstract:
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 is a half-depth image in the event the first sampling rate is selected and a full-depth image in the event the second sampling rate is selected.

Claim (Index 3):
The method of  claim 1 , wherein said sampling the swept-source OCT interference signal at the selected sampling rate comprises:\n in the event the first sampling rate is selected, sampling the swept-source OCT interference signal using a first A/D converter and the k-clock signal, to obtain the sampled OCT interference signal; and in the event the second sampling rate is selected, sampling the swept-source OCT interference signal using the first A/D converter and the k-clock signal, to obtain a first sampled output at the first rate, and also sampling the swept-source OCT interference signal using a second A/D converter and a phase-shifted replica of the k-clock signal, in parallel with sampling the swept-source OCT interference signal using the first A/D converter, to obtain a second sampled output at the first rate, the second sampled output being shifted in time relative to the first sampled output, and combining the first and second sampled outputs to obtain the sampled OCT interference signal.
