Development of Compact, Indigenous Terahertz Systems for Medical Diagnostics and NDT Applications

In this paper, a compact, cost-effective Continuous Wave Terahertz system has been developed and deployed for biological and industrial applications. More than forty Formalin Fixed Paraffin Embedded (FFPE) breast cancer tissues with adjacent normal tissues have been imaged and compared with the histopathology results. The system has also been employed for defect detection and moisture ingression in glass fiber reinforced composites, confirming the potential of the Terahertz system.
