N2 - Millimeter-wave (MMW) imaging has gained significant attention in security, biomedical, and remote sensing applications due to its ability to penetrate obscurants while ensuring non-ionizing interaction with biological tissues. Building on previous work that utilized a charge-coupled device (CCD) camera for up-conversion readout in the near-infrared (NIR) spectrum, this study introduces an advanced imaging system leveraging the HeliCam C4 lock-in camera. This system offers enhanced sensitivity, noise suppression, and real-time imaging capabilities for MMW detection using a novel glow discharge detector (GDD) map configuration. While full MMW imaging results are pending, this paper details the system architecture, methodology, an LED-based prototype validation, and initial GDD/MMW detection experiments.
