e4engineering: New cheaper and quicker microwave imaging for airport security, landmine detection, etc.

From Control & Instrumentation, 02 March 2004, in Machinery & Equipment
"Scientists in the UK are developing a microwave-based technique that can generate high-quality images of hidden objects. The research may lead to the use of microwaves as an alternative to X-rays in airport security checks, building searches, landmine detection and other applications."
As the article says, it isn't that this is a new idea, it's that it could be quicker and cheaper. As we decide that we need to scan everyone everywhere (like at local high schools, etc.) we need to take these things into account. This technology could be a big money maker.
