Abstract[English]
An optical measurement device for performing eccentricity measurement on a product to be subjected to measurement. The optical measurement device comprises a support bracket (11), a light emitting and receiving mechanism (12) and a polarizing device (13), wherein the support bracket (11) is used for supporting said product; the light emitting and receiving mechanism (12) is disposed above the support bracket (11); the polarizing device (13) is disposed between the support bracket (11) and the light emitting and receiving mechanism (12); and the polarization direction of the polarizing device (13) is perpendicular to the polarization direction of a linear polarizing film in said product. Further provided is an optical measurement method.[French]
L'invention concerne un dispositif de mesure optique destiné à effectuer une mesure d'excentricité sur un produit à soumettre à une mesure. Le dispositif de mesure optique comprend une monture de support (11), un mécanisme d'émission et de réception de lumière (12) et un dispositif de polarisation (13), la monture de support (11) étant utilisée pour supporter ledit produit ; le mécanisme d'émission et de réception de lumière (12) est disposé au-dessus de la monture de support (11) ; le dispositif de polarisation (13) est disposé entre la monture de support (11) et le mécanisme d'émission et de réception de lumière (12) ; et la direction de polarisation du dispositif de polarisation (13) est perpendiculaire à la direction de polarisation d'un film de polarisation linéaire dans ledit produit. L'invention concerne également un procédé de mesure optique.[Chinese]
