Patent ID: 7312874

Claim:
An apparatus for determining the color stimulus specification of translucent objects, comprising: an illumination assembly for illuminating the object under test; a detection assembly for capturing the light emitted by said illumination assembly and reflected by said object under test, said detection assembly including a lens and an image sensor and adapted to deliver output signal data in response to the captured light; at least one first polarizing filter configured to polarize the light emitted by said illumination assembly; a second polarizing filter configured to polarize light received by said detection assembly, whereby said first and said second polarizing filters are oriented relative to each other to suppress the light reflected by the surface of the object under test; a display for visualizing said output signal data delivered by said detection assembly; and a control and analyzer device adapted for evaluating the colorimetric data of said object under test; said illumination assembly including a light emitting diode array including a plurality of light emitting diodes emitting light in different wave length portions, each light emitting diode or group of light emitting diodes emitting light in a certain wave length portion being sequentially energized under the influence of said control and analyzer device.
