An apparatus for detecting a leak in one or more blister pockets of one or more blister packs. The apparatus includes a plate for receiving the pack(s), a pressure reducer able to change the pressure around the pack(s) so as to seek to cause deflection of at least one side of the or each blister pocket between at least a first pressure and a second pressure, and an illumination source able to provide a lattice illumination on the or each blister pocket at at least the first pressure and the second pressure. The apparatus also includes an image capture device is which is able to take latticed pictures of each blister pocket at least the first pressure and the second pressure, and processor able to compare the latticed pictures to detect deflection of the blister pocket(s) at the different pressures. |
