Abstract: Multi-fiber laser probes utilize relative motion of fibers and other laser probe elements to preserve small-gauge compatibility while providing for multi-spot beam deliver, or to provide for the selectively delivery of single-spot or multi-spot beam patterns. An example probe includes fibers having distal ends that are movable as a group onto a distal ramp element affixed to a distal end of a cannula, so that the distal ends of the fibers can be moved between a retracted position, in which the distal ends of the fibers are within the cannula or ramp element, and an extended position, in which distal ends of the fibers are guided by grooves or channels of the ramp so as to extend at least partially through external openings in the distal end of the laser probe and so as to be pointed angularly away from a longitudinal axis of the cannula.

Abstract: An optical coherence tomography (OCT) system includes a light source configured to generate an OCT beam and a beam splitter, configured to split the OCT beam into a reference beam and an imaging beam, direct the reference beam toward a reflector, and direct the imaging beam toward a scanner. The system includes a linear actuator, such as a piezoelectric or voice coil, configured to move the reflector to adjust the length of the reference beam and the scanner, configured to scan the imaging beam onto a target surface at a plurality of scan angles, wherein the scanner and target surface are separated by a sample distance that varies at each of the scan angles. The system further includes an OCT controller comprising a processor and instructions stored on a memory, the instructions executable by the processor to cause the OCT controller to generate signals to cause the scanner to scan the imaging beam at each of the scan angles at a first scan rate, and cause the actuator to adjust the length of the reference beam during the scan synchronously with the scan rate to offset the variation in sample distance at each of the scan angles.
