摘要：
We present recent results of sensing and imaging with continuous wave (CW) terahertz (THz) systems. THz waves are generated by Gunn diodes and detection is performed with a Schottky diode and a Golay cell. In order to focus and guide the THz beam, spherical, Fresnel and hyperbolic polyethylene lenses are designed and fabricated. The combination of the Gunn diode and Schottky diode results in a compact and portable system, which is suitable for field inspection. Examples for nondestructive imaging inspection and industrial applications for quality control are presented.
