Abstract:
1. A device for determining the properties of reflective bodies and especially of heterogeneous reflective bodies having: at least one illuminating means which emits light onto a measurement surface; at least one detecting means for recording the light reflected from said measurement surface; wherein at least one of said at least one detecting means comprises a plurality of light-sensitive sensor means, and whereby a measurement value is issuable from substantially each of said sensor means which is characteristic of the light received by each respective sensor means; at least one memory means, in which at least one first predefined threshold is provided; at least one controlling means for controlling the measurement sequence which comprises at least one processing means; whereby a measurement sequence is controllable by said controlling means such that a measurement value of a sensor means is allocated to a first surface type when same exceeds said first threshold; wherein at least two of said sensor means are respectively associated with different locations to be measured on said measurement surface; and wherein said controlling means is configured for issuing at least one statistical parameter which characterizes said first surface type.
