Abstract

The invention relates to a method for optical analysis of a component of an aerosol generating article, the method comprising: —providing a component of an aerosol generating article defining a first end and a second end, the component comprising: o an aerosol forming substrate; o a susceptor in thermal contact with the aerosol forming substrate; —providing a first polarized camera including a sensor to detect polarization information of electromagnetic radiation; —illuminating the component by electromagnetic radiation; —detecting transmitted, infected or refracted electromagnetic radiation from the component by the first polarized camera; —generating a first image of the first end of the component by the first polarized camera, the first image being formed by a plurality of pixels, each pixel of the plurality of pixels containing polarization information about the detected electromagnetic radiation; and—detecting in the first image a position of the susceptor.
