Abstract:
1. A system for improved imaging of eye structures, including the eye anterior segment, comprising: an interferometric measuring arrangement having a measurement arm, a reference arm and a light source that illuminates the measurement arm and the reference arm; an optical element arranged in the measurement arm or the reference arm that influences a polarization state of light in the measurement arm or the reference arm before the light is interferometrically superimposed; a scanning unit arranged in the measurement arm that implements OCT scans; a detector that records produced interference patterns; and an evaluating and documenting unit; wherein the optical element arranged in the measurement arm or the reference arm of the interferometric measuring arrangement produces at least two different polarization states of the light in the measurement arm or the reference arm; wherein the detector records the produced interference pattern in the interferometric measuring arrangement when illuminated with light having at least two different polarization states; wherein a control module has operable connections to the scanning unit, the optical element for influencing the polarization state of the light in the measurement arm or the reference arm, the detector, and the evaluating and documenting unit; and wherein the evaluating and documenting unit reconstructs and combines to at least some extent, spatially superimposing OCT scans from the interference patterns transmitted by the detector and presents and/or stores reconstructed OCT scans.
