The present invention relates to a device and a procedure for the quality
control of in particular finished surfaces wherein the device comprises at
least one illuminating means having at least one light source, its light
directed at a predetermined angle to the measurement surface. A plurality
of at least three measuring means is provided, whereby each of said
measuring means is directed at a different predetermined angle to the
measurement surface and receives a portion of the light reflected from
said measurement surface. Each measuring means comprises at least one
photosensor which emits an electrical measurement signal which is
characteristic of the light received by said measuring means. A control
and evaluation means having at least one processor means and one memory
means controls the measurement sequence, evaluates the measurement results
and derives therefrom a parameter which characterizes the surface. An
output means serves for the outputting of parameters or measurement
results.
