ملخص

A novel imaging system for mm wavelength and THz radiation is presented in this paper. The imaging system is based upon an inexpensive neon indicator lamp or glow discharge detector (GDD) that serves as a pixel in a focal plane array (FPA). It was shown in previous investigations that inexpensive neon indicator lamp GDDs are quite sensitive to mm wavelength and THz radiation. The diameter of the GDD lamp is 6 mm and thus the FPA can be diffraction limited. Using such neon lamps we realize a 4X4 FPA. We used a Polyethylene lens to focus the radiation on the FPA. First imaging results of the novel mm-wave and THz imaging system are presented here. They images are of decent quality. Increasing the resolution of the FPA to 8X8 or 16X16 will improve significantly the quality of the photos in the mm-wave and THz radiation. Our goal is to construct a 128X128 imaging system using the GDD technology.
