We present several preliminary experimental data to demonstrate the potential of terahertz imaging for various commercial applications. Specifically, terahertz images and signatures are presented using terahertz pulsed imaging (TPI™) for green leaves, lung cancer tissues, as well as farm and wild raised salmons. Raw data from these measurements provided the associated refractive indices and absorption coefficients. Time domain reflectometry (TDR) signatures were also collected at terahertz frequencies for integrated circuits. This was done using an electro-optic terahertz pulse reflectometry (EOTPR) system. In all cases, it is demonstrated that discriminatory information can be readily obtained from terahertz images or TDR signals for various organic and non-organic materials.
