Abstract

Recently, wavelength tuning interferometry was suggested as an alternative technique for distance measurements. Compared to partial coherence interferometry, it has the advantages of needing no high precision mechanically moving components and the capability of measuring several distances simultaneously in very short time. We report on first measurements of intraocular distances in human eyes in vivo using a distributed Bragg reflector laser diode with a tuning range of 2 nm. We were able to measure the anterior chamber depth, the lens thickness, the vitreous depth, the axial eye length, and to estimate the thickness of the retina. The resolution is approximately 150 micrometer optical distance.
