Abstract

The properties of terahertz (THz) radiation are well known. They penetrate well most non-conducting media; there are no known biological hazards, and atmospheric attenuation and scattering is lower than visual and IR radiation. Thus THz imaging is very attractive for homeland security, biological, space, and industrial applications. In the other hand, the resolution of MMW images is lower comparing to IR and visual due to longer wavelength. Furthermore, the diffraction effects are more noticeable in THz and MMW imaging systems. Thus the MMW images are blurred and unclear and thus it is difficult to see the details and small objects. In recent experimental work with 8X8 Glow Discharge Detector (GDD) Focal Plane Array (FPA) we were able to improve the resolution of MMW images by using oversampling methods with basic DSP algorithms. In this work a super resolution method with basic DSP algorithms will be demonstrated using the 2X18 double row camera. MMW images with sub wavelength resolution will be shown using those methods and small details and small objects will be observed.
