Question: What is your invention?

Matthew Selwood answered on 7 Mar 2019:

Mine isn’t really an invention, as it were, it is using different ideas and combining them into a single system. X-ray imaging isn’t new, and has been done in hospitals for decades. Aperture imaging is older than electricity, and coded apertures have been around in one way or another for decades. Spectroscopy has been around for a while too. However, all of them have never been combined into one system that can work together to reconstruct an unseen object or objects.
