Abstract

Il riempimento di una sigaretta (3) in osservazione viene controllato intersecando una superficie (14) di una estremità aperta della sigaretta (3) stessa con una lama (9) di luce coerente emessa da una sorgente (4) laser per ottenere una traccia (15) reale di luce, ed analizzando gli eventuali scostamenti e discontinuità di questa traccia (15) reale rispetto ad una traccia (13) teorica rettilinea e continua, ricavata congiungendo due punti (B, C) estremi della traccia (15) reale stessa, per ottenere un segnale di accettabilità o meno della sigaretta (3) in osservazione.(Figura 3).
