One of the solutions for spectral-domain OCT (SD-OCT) system to improve its functionalities is to have multiple spectrometers to achieve high speed or sensitivity, but the multiple spectrometers require the performance of the spectrometers to be carefully matched. In this study, we introduce and demonstrate a numerical method to calibrate the performance of multiple spectrometers. The calibration was done by remapping the spectrum of the spectrometers and assessed by a merit function based on phase subtraction. This numerical method allowed us to match the performances of the two spectrometers by over 99%.
A robust multi-volume three-dimensional (3D) registration algorithm is introduced to improve the contrast of optical coherence tomography (OCT) volumes. Our method involves registering multiple volumes to a selected reference volume to correct for the translational and rotational differences between each target and the reference volume and averaging the registered volumes. We tested our registration algorithm on the volumes obtained from three OCT systems with different field-of-views and resolutions. To demonstrate its accuracy, our developed method is evaluated using two different metrics, and its advantages over the other registration algorithms and its limitations are discussed.
