Abstract
Method for determining a refractive index of an object in which the object is illuminated with a slit pattern of illumination light to form an optical section of the section of the object and the optical section is observed in two directions to determine apparent thickness of the optical section in these directions. Operations are carried out to obtain the refractive index of the object from the apparent thickness of the optical section.
