Patent ID: 8596786

Claim:
An arrangement for measurement of a movement of an eye, comprising: a first two-dimensional spatially resolving detector that repeatedly images a potential motion field of the eye in overview images at a first image refresh rate; a second two-dimensional spatially resolving detector that repeatedly images a respective segment of the eye in sectional images at a second image refresh rate, which is higher than the first image refresh rate; a data processor that determines a first intermediate shift between two overview images, and a second intermediate shift between two sectional images, and that determines a movement of the eye though interlinking of said shifts; a first light source that illuminates the potential motion field of the eye with incoherent light; a second light source that illuminates the respective segment of the eye with coherent light such that a speckle pattern occurs in the respective segment through interfering, coherent light, scattered at the eye; and wherein the second detector is structured to record at least one part of the speckle pattern in the respective sectional image.
