Hand-held measurement device for capturing the visual impression of a measurement object

A hand-held measurement device for capturing the visual impression of a measurement object, comprising:

• a measurement array, comprising:
• an arc body;
• a number of illumination means supported by the arc body for applying illumination light to the measurement field in at least three illumination directions in relation to a device normal;
• a number of pick-up means supported by the arc body for capturing the measurement light in at least one observation direction in relation to the device normal, and
• a beam splitter supported by the arc body;
• an electronic controller, and
• a housing,
• wherein said housing accommodates the measurement array and the electronic controller and comprises a measurement opening through which a measurement field on a surface of a measurement object is illuminated and the measurement light reflected by the measurement field is picked up,
• wherein the at least three illumination directions and the at least one observation direction lie in a system plane,
• wherein at least one spectral pick-up means is embodied to spectrally gauge the measurement light reflected by the measurement field in a locally integral way, and at least one imaging pick-up means is embodied to gauge the measurement light in a locally resolved way,
• wherein the imaging pick-up means is also embodied to gauge the measurement light in terms of colour, and in that the spectral pick-up means and the imaging pick-up means are arranged such that they receive the measurement light reflected by the measurement field from the same observation direction,
• wherein the spectral pick-up means comprises a spectrometer as a light detector and the imaging pick-up means comprises a digital colour camera as a light detector,
• wherein the beam splitter divides a pick-up beam path, which in sections is a common beam path, and directs it onto the spectrometer on the one hand and onto the colour camera on the other hand, and
• wherein the beam splitter is arranged such that it is rotated about the common beam path and out of the system plane by essentially 45° such that the measurement light for the colour camera is guided out of the system plane to equalize s and p polarization components of the measurement light which are orthogonal to the system plane.
