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.

Abstract: Split Integration Mode (SIM) acquisition schemes are presented that enable optical coherence tomography (OCT) imaging at multiple rates. SIM enables a system and method of operation having a first mode and a second mode, wherein the fundamental acquisition rate of the detector is the same in the two modes, but wherein the generated signals in the second mode are digitally combined prior to signal processing to create a data set with an effective acquisition rate less than the fundamental acquisition rate.
