Calibrating intensity values of optical coherence tomography (OCT) images helps to extract valuable tissue information, such as the attenuation coefficient. To achieve this, knowledge of focus position and Rayleigh length is crucial. We study the potential of obtaining the focus position from an OCT scan acquired with a single focus setting using the system’s longitudinal chromatic aberration. Different focus positions for sub-spectrum reconstructed OCT images are realized by taking advantage of the chromatic focal shift. Ratios of these sub-spectral images are used to estimate the focus position. High-resolution B-scan reconstruction is demonstrated by coherently combining sub-spectrum confocal function corrected B-scans, followed by OCT attenuation coefficient imaging. Additionally, we present an approach to experimentally identify the chromatic focal shift from OCT data itself.
