Means for illuminating a measurement surface and device and method for determining the visual properties of objects

Device for determining the properties of reflective objects comprising:

• at least one first optical means configured as an illuminating means and with which light is emittable onto a measurement surface;
• wherein at least said first optical means comprises at least one aperture means and at least one control means arranged in the path of radiation, wherein said first optical means includes at least one radiating means having at least two sources of radiation, wherein the radiation emitted by said at least two sources of radiation is directable to said aperture means;
• at least one second optical means configured as detector means and with which the light reflected from the measurement surface is measurable;
• wherein at least one measurement value which is characteristic of at least a portion of the received light is outputable by said detector means;
• at least one memory means;
• at least one control means for controlling the measurement sequence;
• wherein at least one characteristic parameter which characterizes the measurement surface is determinable.

Method for determining the properties of reflective objects utilizing a device comprising:

• at least one first optical means configured as an illuminating means and with which light can be radiated onto a measurement surface;
• wherein at least said first optical means comprises at least one aperture means and at least one scattering means arranged in the path of radiation, and wherein at least said first optical means comprises at least one radiating means having at least two sources of radiation, wherein the radiation emitted by said at least two sources of radiation is directable to said aperture means;
• at least one second optical means configured as detector means;
• at least one memory means;
• at least one control means for controlling the measurement sequence;
• wherein light from at least one source of radiation is directed to the aperture means and radiated onto the measurement surface;
• wherein said detector means records at least a portion of the light reflected from the measurement surface and outputs at least one measurement value which is characteristic for at least a portion of said received light;
• and
• wherein said control means determines at least one characteristic parameter which characterizes at least one portion of the measurement surface based on a command sequence stored in the memory means.
