Abstract

 

Correlation between the optical density of the crystalline lens nucleus in terahertz range with its density,
determined according to the L. Buratto classification was revealed. Lens fibers infiltration caused by senile
cataract increases the lens reflectivity in the THz range. The temporal structure of reflected THz signals allows
determining the spatial distribution of crystalline lens density.

Keywords: terahertz spectroscopy, terahertz tomography, ophthalmology, cataract diagnosis.
