Abstract:
Device for the quality control of finished surfaces, comprising:at least one illuminating means having at least one light source that directs light at a predetermined angle to the measurement surface which is a part of the surface to be measured; a plurality of at least three measuring means, with each of said measuring means being directed at a respectively different predetermined angle to said measurement surface and receiving a portion of the light reflected from said measurement surface, and with each of said measuring means having at least one photosensor which emits an electrical measurement signal characteristic of the light received by said measuring means; at least one control and evaluation means provided for the control of the measurement sequence and the evaluation of the measurement results and which comprises at least one processor means and at least one memory means; an output means; wherein said evaluation means evaluates said measurement signals and derives therefrom at least one parameter which characterizes said surface; and wherein an angle spacing from a first retaining means to a second retaining means is essentially equal to an angle spacing from the second retaining means to a third retaining means.
