Abstract: In order to measure a cornea with the aid of a projection (S11) of a two-dimensional reference pattern onto the cornea and of a detection (S12) of the reflection pattern reflected by the cornea by virtue of the reference pattern, a plurality of different reflection images of one or more reflection patterns reflected by the cornea are stored (S13). For points on the cornea a phase value of the reflection pattern is respectively calculated on the basis of intensities respectively measured in the stored reflection images at a pixel corresponding to the relevant point. At least one measured geometrical value of the cornea is calculated (S2) on the basis of the calculated phase value. The measurement of the cornea on the basis of a plurality of different reflection images of one or more reflection patterns reflected by the cornea enables a continuous measurement of the cornea in which corresponding pixels are acquired and evaluated for each point on the cornea.

Abstract: A lamellar grating interferometer is described, in which the light beams are collimated and focused onto the grating by means of mirror 9, which at the same time serves for collecting the light reflected from the grating. In this case, the light beam of a white light source 1 is first collimated by means of first lens 2, and subsequently passed through a sample cuvette 3. The transmitted light beam is subsequentlyy focused and coupled by another lens 2 into a fibre 17. The light to this fibre 17 is subsequentlyy directed towards a mirror 9, reflected from this mirror 9 onto a grating 11, which forms part of a lamellar grating interferometer which is realised by means of a micro electro mechanical device MEMS 7, which is mounted on a MEMS holder 6, as is the fibre 17. The light reflected from this grating 11 is reflected onto the same mirror 9, and focused and coupled by this same mirror 9 into a second multimode fibre 18, which is also fastened to the holder 6.

Abstract: In the embodiment described in the specification, a fuel injection pump nozzle which is received in a recess in a cylinder head is mounted on the cylinder head by a flange which engages a bearing surface on the surface of the cylinder head surrounding the recess. This prevents application of mounting forces to the sealing contact surface in the cylinder head recess, thereby avoiding critical stresses in the region of the cylinder head near the combustion chamber.
