Abstract

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%.
