摘要： The invention relates to a method for optically testing containers, in which a container (10) is conveyed by means of a transport device (30), whereby an image of a side wall surface of the container (10) is generated by means of an inspection unit (40) comprising a camera unit (20) and an illumination unit (34). An inspection volume (24) is spanned by several correspondingly arranged inspection units (40), in which an image of the entire side wall surface (26) of the container (10) is generated in a transmitted light method, an incident light method and/or a dark-field method.
