| titleOfInvention | Apparatus for measuring refractive index |
| abstract | Apparatus for the measurement of optical properties of a quasi cylindrically - symmetric transparent object (2), particularly the radial refractive index profile of an optical fibre preform, comprises source means (11) for providing a source of electromagnetic radiation, illumination forming means for forming an illuminating beam (41), region selecting means for selecting a localised radial region (42), region scanning means for scanning the localised radial region (42) through a range of radial positions, reflection detecting means for detecting a reflected beam (43), beam measuring means for measuring the component of the position where the reflected beam (43) leaves the transparent object (2), supporting means which causes the illuminating beam (41), the reflected beam (43) and an axis of rotational symmetry (1) of the transparent object (2) to lie in a measurement plane, and angle altering means for altering the angle of incidence of the illuminating beam (41) on the transparent object (2). <IMAGE> |
