Abstract: An arrangement for increasing measurement accuracy in three-dimensional measurement of objects, and a method for three-dimensional measurement of objects. The arrangement has a base for placing thereon an object to be measured, a device for emitting light beams toward the object, a device for detecting light beams reflected by the object and the substrate, and a device for determining 3D data based on travel time measurements and/or triangulation of the emitted light beams and reflected light beams, and for determining dimensions of the outer shell of the object. A measurement inaccuracy range affected by interferences and forming on the substrate is bridged and spaced from the actual measurement position by a transparent plate with a predetermined thickness arranged between the at least one object and the substrate, so that the determination of dimensions of the outer shell of the object is only partially possible and becomes more precise.

Abstract: A process for hardening an annular groove of a piston head of a piston of an internal combustion engine by means of laser beams, in which, at least the annular groove to be hardened is provided before or directly during the hardening process with a coating which absorbs the energy of laser beams. The coating is subsequently irradiated by the laser beams. The absorbing layer can be a manganese phosphate coating or is formed in situ by treating the component surface with a process gas comprising oxygen and inert gas. Furthermore, the laser beams are directed at the piston during hardening at an oblique angle to the direction of rotation. The advantages achieved are avoidance of reflections and undesirable hardening of the bottom of the groove, an increased degree of absorption and reduced distortion of the piston.
