We present a new non-invasive air-photonic-based
method of terahertz (THz) field imaging inside a parallel plate
waveguide. The method is based on THz field-enhanced second
harmonic generation of the fundamental laser beam in an
external electric field. We also demonstrate the direct
measurements of the frequency-dependent reflection coefficient
at the end of the waveguide.
