Physicist Sees Through The Opaque

December 18, 2009

T-rays may make X-rays obsolete as a means of detecting bombs on terrorists or illegal drugs on traffickers, among other uses, contends a Texas A&M physicist who is helping lay the theoretic groundwork to make the concept a reality. In addition to being more revealing than X-rays in some situations, T-rays do not have the cumulative possible harmful effects. Alexey Belyanin focuses his research on terahertz, otherwise known as THz or T-rays, which he says is the most under-developed and under-used part of the electromagnetic spectrum. It lies between microwave radiation and infrared (heat) radiation. Credit: Texas A&M University
