Ultrafast, sensitive, and inexpensive 3 dimensional MMW/THz imaging system using Glow Discharge Detector Array and CCD camera based on upconversion to visual band

A 3 dimensional MMW/THz imaging system using the upconversion mechanism of glow discharge detectors is demonstrated. The MMW/THz radiation is converted to the visual band using an inexpensive glow discharge detector array and basic optical CCD camera to yield the MMW/THz image.
