These are not even similar to your IR experiments that are designed to direct an IR beam at a target. The principle of operation is different, and the results are definitely different, as is expected from completely different instruments.

Yes, you're right. I think you can convert an IR laser termometer for to find buried metals. But also consider the beam as an IR "camera".
