A new optical instrument for `in vivo' analysis of ocular tissue is presented. The instrument is based on the well know dynamic light scattering technique. Using optimal beam shaping the analysis can be achieved in the cornea and in the anterior chamber as well as in the lens and in the vitreous with high spatial resolution and sensitivity. In order to obtain high beam quality, to provide modularity and galvanic insulation of the instrument, monomode optical fibers are used to guide the excitation and the scattered light. Following a description of the instrument, preliminary `in-vivo' measures are discussed in order to asses the performance of the instrument in ophthalmology diagnostics

Abstract
A new optical instrument for `in vivo' analysis of ocular tissue is presented. The instrument is based on the well know dynamic light scattering technique. Using optimal beam shaping the analysis can be achieved in the cornea and in the anterior chamber as well as in the lens and in the vitreous with high spatial resolution and sensitivity. In order to obtain high beam quality, to provide modularity and galvanic insulation of the instrument, monomode optical fibers are used to guide the excitation and the scattered light. Following a description of the instrument, preliminary `in-vivo' measures are discussed in order to asses the performance of the instrument in ophthalmology diagnostics
