Abstract

Il riempimento di una sigaretta (3) viene controllato tramite un dispositivo ottico (1), il quale è provvisto di un sensore (12) e di una lente (7) a fuoco (9) fisso, e presenta un piano (10) di messa a fuoco determinato ed una profondità di campo sostanzialmente nulla; la sigaretta (3) viene disposta con una propria estremità aperta in corrispondenza del piano (10) di messa a fuoco, ed il sensore (12) rileva il contrasto dell'immagine prodotta dalla lente (7). (Figura 1)The filling of a cigarette (3) is controlled by an optical device (1), which is equipped with a sensor (12) and a fixed focus lens (7) (9), and has a plane (10) of determined focus and a substantially zero depth of field; the cigarette (3) is arranged with its own open end in correspondence with the plane (10) of focus, and the sensor (12) detects the contrast of the image produced by the lens (7). (Figure 1)
