Eye shape using partial coherence interferometry, autorefraction, and SD-OCT. [PDF]
Optom Vis Sci, 2015 ABSTRACT Purpose 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.

Optics Express, 2001 Dispersive samples introduce a wavelength dependent phase distortion to the probe beam. This leads to a noticeable loss of depth resolution in high resolution OCT using broadband light sources. The standard technique to avoid this consequence is to balance the dispersion of the sample byarrangingadispersive materialinthereference arm.
