This is the prototype that was testes my Raytheon and their representatives from MIT and JIEDDO It was tested in 2011 and never used, because JIEDDO and the US Government does not want a explosive detector. I have the documentation , signed this is first generation test and unit of the technology as you can see very crude but it worked very well In fact I was not even present for the test. I was given a test result sheet and told them what was detected for sure this was the best test ever done Three other people ran the test, I was put in an illation room and There was no way to cheat on this test. MIT Security and Raytheon ran the test It may be possible they have use my technology. Bill Birchard
