SYSTEM FOR OPTICAL MEASUREMENT OF AN OBJECT COLORIMETRY

摘要

The invention concerns a system for measuring the colorimeter of objects comprising an illuminating source (SO), a detecting device (CA) supplying electric signals representing the image of the illuminated tooth/teeth. The illuminating source comprises at least three light-emitting diodes (DL1 to DL3) emitting light rays of different and sequentially controlled wavelengths. A central unit (UC) receives, from the detecting device (CA), each time the object is illuminated, the image of the light reflected and received by the detecting device. The central unit computes, for each image, the level of each colour and determines, for different points, standard colorimetric coordinates. The invention is useful for measuring the colour of teeth.
