Axial localization of luminophores by partial coherence interferometry [PDF]
SPIE Proceedings, 2004 We propose a solution for increasing the axial resolution of confocal microscopes. In the experimental set-up described in this paper an interference phenomenon between two counterpropagating beams is used to determine the axial position of a luminophore.

Eye shape using partial coherence interferometry, autorefraction, and SD-OCT. [PDF]
Optom Vis Sci, 2015 Peripheral refraction and retinal shape may influence refractive development. Peripheral refraction has been shown to have a high degree of variability and can take considerable time to perform. Spectral domain optical coherence tomography (SD-OCT) and peripheral axial length measures may be more reliable, assuming that the retinal position is more ...

Validation of a partial coherence interferometry method for estimating retinal shape. [PDF]
Biomed Opt Express, 2015 To validate a simple partial coherence interferometry (PCI) based retinal shape method, estimates of retinal shape were determined in 60 young adults using off-axis PCI, with three stages of modeling using variants of the Le Grand model eye, and magnetic resonance imaging (MRI).
