Abstract:
Methods, systems and apparatuses are disclosed for interrogating characteristics of a substrate material surface and sub-surface by evaluating: 1) sum frequency output beams produced by combining an optical source input and a Terahertz source input, and 2) Terahertz second harmonic frequency output from a Terahertz source input.
