Device and method for analyzing the apparent colour and the gonio reflectance of an object

A device for analyzing the apparent colour and the gonioreflectance of an object comprises: a supporting case (13), designed to be positioned in the proximity of a surface of the object to be analyzed; spectrometer means (6,7), mounted within the supporting case (13); optical means (9, 10), arranged within the case of the device, for focusing on the aforesaid spectrometer means (6, 7) both the radiation reflected by a selected area (T) of the surface of the object to be measured (1) and the radiation reflected by the reference surface (11); and means for measuring the gonioreflectance of the selected area (T) of the surface to be analyzed, said means comprising a battery of LEDs (4), each designed to emit a substantially collimated beam of light and send it onto the selected area (T), and a battery of photodetectors (5), each designed to collect a substantially collimated beam of light coming from the selected area (T), each of said LEDs (4) being pre-arranged for being turned on independently of the others; and electronic means (12) for reading and processing the signals at output from said spectrometer means (6, 7) and from said photodetectors (5).
