A device for non-destructive inspection of containers (22) of food products
comprises an emitter (24) emitting a divergent radiation beam, with vertical
axis and a pair of detectors (26) detecting the radiation coming from the
emitter (24) and passing through a container (22) to be inspected;
the radiation detectors (28, 30) are linear detectors and are spaced so
as to receive radiation (32, 32) emitted by the emitter (24)
according to two different directions.
