| titleOfInvention | Method for determining the refractive-index profile of a cylindrical optical object |
| abstract | The invention relates to a method for determining an index-of-refraction profile of an optical object (22), which has a cylindrical surface (26) and a cylinder longitudinal axis (25), said method comprising the following method steps: (a) scanning the cylindrical surface (26) of the object (22) at a plurality of scanning locations (23) by means of optical beams (21) which are incident perpendicularly to the cylinder longitudinal axis (25); (b) capturing, by means of an optical detector (7; 8), a location-dependent intensity distribution of the optical beams (21) deflected in the optical object (22); (c) determining the angles of deflection of the zero-order beams for each scanning location (23) from the captured intensity distribution, comprising eliminating beam intensities of higher-order beams from the intensity distribution so that an angle-of-deflection distribution is obtained for the zero-order beams, and (d) calculating the index-of-refraction profile of the object (22) on the basis of the angle-of-deflection distribution, wherein method steps (a) and (b) are carried out with light beams having at least two different wavelengths and, in order to eliminate beam intensities of higher-order beams, same-location intensities of the intensity distributions for the different wavelengths are mathematically processed with each other, more particularly multiplied by and/or added to each other. |
