  • Abstract
  • Look Inside

The Foucault knife edge test was carried out in human eyes, using a Nikon-F camera with bellows attachment and 200 mm/4 lens, in front of which a small mirrow was attached.

The knife edge cutting of the ray from the eye was performed by means of parallel move-ment of the mirror which reflected the ray from a light source into the eye.

The spherical aberration, coma and oblique astigmatism of the eye were analysed by exa-mination of the patterns of the Foucault-shadow on the cornea.

The relations between the aberrations and the patterns of the shadow were confirmed theore-tically by ray tracing method.
