Very impressive, as always from bunnie. The background/introduction post [1] is informative for people like me who haven't kept up. Basically he has invented (as far as I understand?) the "IRIS" technique to inspect chips that are still packaged.
This should make it easier to look "under the hood" of system-on-chips and such, to see if there perhaps are units that are unaccounted for. If someone knows more about the motivation/goals with the research that would be interesting to have further explained than the post(s).
This post is about the lighting needs the imaging requires, and the very detailed design of a mechanized light source positioning system.
Also, there seems to be an actual paper about the technique over on arXiv [2] if you want more academics.

The organizations that need to ensure the chips they receive are 'as expected' don't know how those chips may differ or why (or even that they will.) They just need to prove that they received what they ordered, on every unit.

I work in medical devices. One of the changes in the new FDA guidance for cybersecurity is a greater focus on verifying the integrity of your supply chain, both physical and software. This type of inspection could be a potential mitigation of some of those verification issues.
This post is tagged with Precursor, so I assume this project is to add another level of assurance about supply chain integrity for the components going into the precursor.
