f) the length X of the ray path starting from the pulsed light source (03) via the measurement point to the light sensor (04) is derived from the measured value F1 and the specific speed of light c at which the light propagates in the medium along the ray path.
The present invention relates to a method for operating an ophthalmological analysis system having a slit projection unit for slit illumination of the eye and a Scheimpflug camera for taking digitized sectional images of the eye, slit projection unit and Scheimpflug camera being mounted so that they may pivot jointly rotating around an axis which is essentially coincident with the optical axis of the eye. In a first position of slit projection unit and Scheimpflug camera, a recording of a sectional image of the eye is made and stored as the first image data set. Subsequently, slit projection unit and Scheimpflug camera are pivoted rotating at least once and fixed in this particular subsequent (second, third, fourth, . . . ) position. In the particular subsequent (second, third, fourth, . . . ) position of slit projection unit and Scheimpflug camera, a recording of a sectional image of the eye is made and stored as the subsequent (second, third, fourth, . . . ) image data set. A multidimensional description model of at least one component of the eye is derived through image data analysis of the different image data sets in a digital image data analysis device and stored as the resulting data set. The resulting data set is output in suitable form to a data output device.
The invention relates to a measuring device (01) for measuring the refraction properties of optical lenses (07), especially spectacle glasses, comprising a measuring light grid (20) for producing a plurality of light beams (16) which are deflected by the lens (07) as a result of refraction of light, and comprising a measuring light detector (12) on which the deflected light beams are projected and are there recorded electronically, and comprising an evaluation device in which the refraction properties of the lens (07) are determined from the measurement signals of the measuring light detector (12), wherein a screen (10) comprising a plurality of light passage openings (23, 24) is arranged between the lens (07) to be studied and the measuring light detector (12), wherein the light beam (16) produced by the measuring light grid (20) and deflected at the lens (07) by refection of light is projected through the various light passage openings (23, 24) of the screen (10) along separate ray paths onto the measuring light detector (12).
