    • 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 optica! 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,
    • 一种用于测量光学可变的光学特性的方法标记施加到对象,所述方法包括照明所述光学可变标记,以便形成通过在由反射的第一视角和第二光标记反射的第一光的步骤 在第二视图角度标记,具有不同光谱的组合物作为光学可变的结果,第一和第二灯标记,折射第二通过光学单元的反射光,从而将第二重定向反射朝向在光学传感器的光,捕获所述第一 光,并同时在光学传感器的第二折射光; 和光学可变的确定性采矿光学性质的标记基于捕获的第一和第二光线。
