@ Asker Exactly as I said! The presence of this device seems to prove it conclusively — and it is perfectly standard practice to check soemthing automatically and then to verify it by manual inspection later — for example, in case of doubt / ambiguous results, or sampling statistically as a cross-check.
Whatever it is certainly implies some kind of automated procedure, for it to then be contrasted with a 'manual' one; and it appears that the automated one precedes the manual one, which again is only logical.

I haven't had any feedback from the client, but I did find the presence of a "mireuse" device in a related document, which leads me to believe this is some kind of automated vs. manual procedure. But I am still not completely sure.

Unfortunately I've left it late to get an answer from the client since there's a time difference at this is rush. I am going to use examination with a note in the file. I'll update if I get any interesting feedback.

For what it's worth... Mirage is usually a manual visual inspection - a process where light is shone through a device, which an operator looks at in front of black and white backgrounds in turn. In my experience it's often the stage of looking at a filled syringe before passing to the secondary packaging step, but obviously it could refer to all sorts of other things with a transparent packing layer. Joan is facing what I never have seen in many years of translating many docs about these processes - both "mirage" and "inspection visuelle" in the same doc.

In the olden days... Mirer meant to look through the shell of an egg by holding it up against a candle, to see if the chick was developing inside or not.
I suspect this is soemthing similar here; is this perhaps some automated process where a light is shone through a semi-transparent packaging and a machine detects whether something is present or not? This could have some connection with the clue of 'surpochage'? I feel sure a lot more of your wider context would make it clear; but on the face of it, it would appear that they are contrasting some kind of machine optical process with a human visual inspection. Once you have sorted that out, you can start looking for a term.
