Abstract:
An apparatus for testing a cigarette head (16), having a light source (11) and an optical system (13-15) for producing at least one region (37, 38), irradiated with light, on a cigarette head (16), and having a detector (19), for receiving light (20) reflected by the cigarette head (16), which is arranged so that the irradiating light and the received reflected light (18, 20) run at an angle to one another, and so that the irradiated region (37, 38) can be imaged on the detector (19),said apparatus further comprising an evaluation device which evaluates a signal generated by the detector (19) in order to determine a possible deviation in a position, of the image (43, 44, 45) of the irradiated region (37, 38), from an expected position of an image of a corresponding region of an ideal cigarette head, in order to determine, from the deviation, the distance of the irradiated region (37, 38) from a desired position thereof; and an optical system (13) for producing a structured light pattern on the cigarette head (16).
