you have the main companies that produce the smartphones.’ Teledyne Dalsa’s Boridy says the benefits of


3D imaging are varied. ‘It is mainly used in the inspection of parts, and those parts can be related to industries from food to metal to semiconductors,’ he explained. ‘It is also useful for quality assurance and validations, and very useful for measurements that 2D cannot give us. Oſten, you need to verify parts or tolerances and you need to inspect if there are parts missing. ‘For example, if you’re inspecting a BGA


chip and want to know if the balls are all aligned at the same level or if there are any missing, 2D can do that to a certain degree, but it cannot give the height if the balls are all at

the same height. 3D is able to give you that, so it complements 2D.’


Limitations in 2D Henzler concurs. ‘You need a 3D system if you want to measure height or deformations of freeform parts with freeform surfaces,’ he said. ‘Tere is no way to set up a 2D system that readily detects all the defects of such a part, especially if it’s not just a scratch but a variation of the thickness of the material somewhere on the part – you cannot detect this with 2D. ‘Another point is that if you have very low


contrast, for instance, when inspecting rubber tyres, it’s very difficult to inspect this with 2D cameras. It’s much easier if you just take the
