Paper Abstract
In this paper, we introduce the self-mixing phenomenon in terahertz quantum cascade lasers (THz QCLs) and present
recent advancements in the development of coherent THz imaging and sensing systems that exploit the self-mixing effect.
We describe an imaging method which utilises the interferometric nature of optical feedback in a THz QCL to employ it
as a homodyning transceiver. This results in a highly sensitive and compact scheme. Due to the inherently low penetration
depth of THz radiation in hydrated biological tissue, imaging of superficial skin is an ideal application for this technique.
We present results for imaging of excised skin tissue, showing high-contrast between different tissue types and pathologies.
