The invention relates to a method for testing cigarette heads, at least one region of a cigarette head being irradiated with light, and light reflected by the cigarette head being received by a detector in such a way that irradiating and received reflected light run at an angle to one another, the irradiated region is imaged on the detector and a signal generated by the detector is evaluated. Such known methods have the disadvantage that they are inaccurate and do not permit exact statements on the state of cigarettes. The invention is therefore based on the problem of improving the testing of cigarettes. It solves this problem by virtue of the fact that, when evaluating, a possible deviation, in particular a distance, of the position of the image of the irradiated region from an expected position of an image of a corresponding region of an ideal cigarette head onto the detector is determined, the deviation being used to determine the distance of the irradiated region from a desired position of this region. The invention also relates to an apparatus for carrying out this method.
