ABSTRACT
We report the use of a compact continuous-wave sub-terahertz system for inspection applications, using electronic generation and detection methods. A combination of a Gunn diode emitter, a Schottky diode detector, and a polyethylene Fresnel lens provides line-scan images at 0.2 m/s with a data acquisition rate of 512 points/s. Examples of the measurement of NASA’s insulating panels and applicability of the technology to other nondestructive testing applications are presented and discussed.
