Comparison of a new biometer using swept-source optical coherence tomography and a conventional biometer using partial coherence interferometry. [PDF]

open access: goldPLoS One, 2018
The aim of this study was to compare the axial lengths (ALs) using a new biometer with swept-source optical coherence tomography (Argos) versus ALs using a conventional biometer with partial coherence interferometry (IOL Master, version 5). The ALs in 48

Dispersion Effects in Partial Coherence Interferometry: Implications for Intraocular Ranging [PDF]

open access: bronzeJournal of Biomedical Optics, 1999
In nondispersive media, the minimum distance that can be resolved by partial coherence interferometry (PCI) and optical coherence tomography (OCT) is inversely proportional to the source spectral bandwidth. Dispersion tends to increase the signal width and to degrade the resolution.
