A DEVICE AND A METHOD FOR CHARACTERISING A CHROMATIC PROPERTY OF FOODSTUFF

摘要

The present disclosure provides a device for characterising a chromatic property of foodstuff. The device comprises a light source arranged to emit light having at least two wavelengths or wavelength ranges. The light source is further arranged to direct the light to a surface of at least the foodstuff. The device also comprises a detector positioned to detect at least a portion of reflected light and arranged to generate an output that is indicative of an intensity of detected reflected light. The device is arranged such that respective outputs are generated for the at least two wavelengths or wavelength ranges. A relation between the output for one of the at least two wavelengths or wavelength ranges and the output for the other or another one of the at least two wavelengths or wavelength ranges is indicative of the chromatic property of the surface of the foodstuff.
