    摘要： A device for removing material from a workpiece, in particular for removing a hard substance, such as tooth enamel or dentine from a tooth, or for removing ceramic materials, has a laser for irradiating the workpiece in a locally limited ablation area where material is removed, and a handling part (1) which receives the laser or is connected thereto by an optical fiber element or by a mirror arrangement. The handling part (1) is used to position the laser beam (3) in the ablation area and has a distance measurement device (11 to 15, D1, D2) to monitor the depth of material removal. While the material is being removed, the distance measurement device (11 to 15, D1, D2) measures the distance to the workpiece surface in the ablation area and therefore the depth of material removal by means of the material-removing laser or of a measurement beam (11) generated by another laser.

    摘要： A method and apparatus for the ablation of hard biological material, such hard dental material, using a rapidly pulsed laser employ a crystal disposed in the propagation path of the laser radiation, the crystal being disposed at the laser output and serving as an interface with an optical conductor which conveys the laser radiation to the treatment site. The crystal smooths the time/intensity characteristics of the pulsed laser radiation to the extent that transmission to the treatment site using optical wave guides is possible. Additional protective features are provided to prevent the ablated biological material to destroy the exposed optical end surfaces of the treatment applicator. Additional design features improve the ergonomic efficiency of the handpiece and its ability to be sterilized.

    摘要： A method and apparatus for the ablation of hard biological material, such hard dental material, using a rapidly pulsed laser employ a crystal or absorber film disposed in the propagation path of the laser radiation, the crystal or absorber film being disposed at the laser output and serving as an interface with an optical conductor which conveys the laser radiation to the treatment site. The crystal or absorber film smooths the time/intensity characteristics of the pulsed laser radiation to the extent that transmission to the treatment site using optical wave guides is possible. Additional protective features are provided to prevent the ablated biological material to destroy the exposed optical end surfaces of the treatment applicator.

    摘要： A method for determining a combined data record for an object using individual data records based on individual scans of the object, the scans being measured using at least one sensor. To avoid accumulating errors and allow individual data to be rectified or corrected, first partial scans of the object are measured using at least one first sensor and are aligned relative to one another and/or corrected using second partial scans performed by at least two second sensors that are stationary relative to one another, and the individual data records for the combined data record are determined from the aligned and/or corrected partial scans.
