Zusammenfassung: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.
