The invention relates to a method and a device for sintering objects by means of time-resolved detection of two- or three-dimensional surface profiles and, optionally, by means of temperature measurement in a high temperature furnace on the basis of optical measurement methods. During sintering, each surface point on an object can be measured for its position and, optionally, its temperature, and a change can be determined by successive measurements. The measured change additionally permits control of the sintering regime. The method comprises the steps of: placing an objectinto a high temperature furnace; heating the furnace; generating a two- or three-dimensional surface profile at least of a subregion of the objectby: irradiating the objectwith light from a light source; detecting the light scattered by the objectwith the aid of a detector; determining the geometric surface profile from the detected light.
