LLP and FTIR both give great results, but unfortunately lack DI’s ability to do fiducials, a feature I find quite interesting. So, while I’m sitting here without funds to build an actual table I thought I’d test a concept I had.
My first idea was to try and create a sort of FTIR effect inside an acrylic “puck”, but not having any acrylic I looked around for what I did have, lots of old useless CD’s
After some playing around I came up with this method which produced some promising results.
There’s definitely room for improvement, but for a proof of concept with my rather low-end make-shift setup I think the results are definitely promising.
Hope someone else finds this interesting, and I can’t wait to seem someone try this with more powerful setup (AlexP? )
