Abstract
The design and testing of a close range Passive Millimeter Wave (PMMW) scanning thermal imager is described. While close range PMMW imaging has previously been applied to concealed weapon detection at ranges of a few meters, the imager under development here is designed to focus on targets at a range of a few tens of centimeters. In particular, the main design aim is to produce high resolution thermal maps suitable for medical imaging applications. Imaging at MMW frequencies offers greater- penetration depths in lossy dielectric media than conventional infrared (IR) imagers, although there is an obvious trade-off in spatial resolution.
