Abstract
A device for determining the properties of reflective bodies has at least one illuminator that emits light onto a measurement surface, at least one detector for recording the light reflected from the measurement surface, the at least one detector includes a plurality of light-sensitive sensors. Substantially each sensor issues a measurement value characteristic of the light received by each respective sensor. Also included is at least one memory, having at least one first predefined threshold, at least one controller for the measurement sequence which includes at least one processor, whereby a measurement sequence is controllable such that a measurement value of a sensor is allocated to a first surface type when same exceeds the first threshold, wherein at least two sensors are respectively associated with different locations to be measured on the measurement surface, and wherein the controller is configured to issue at least one surface characteristic statistical parameter.
