Document Type and Number:

Japanese Patent JP2013531307

Kind Code:

A

Abstract:

A method for measuring optical properties of an optically variable marking applied on an object, the method including the steps of illuminating the optically variable marking so as to form a first light reflected by the marking at a first view angle and a second light reflected by the marking at a second view angle, the first and second lights having different spectral compositions as a result of the optically variable marking, refracting the second reflected light through a optical unit so as to redirect the second reflected light toward an optical sensor, capturing the first light and the second refracted light with the optical sensor simultaneously; and determining optical properties of the optical variable marking based on the captured first and second lights.
