Abstract

We describe the status of, and present the first imagery obtained using, an active uncooled mm-wave microbolometer-based imaging system. The microbolometers consist of 2 mm x 6 mm x .02 mm Nb films, coupled to the incident field by annular slot antennas. The system frequency is centered at 94 GHz. Imagery has been obtained using a mechanically scanned primary mirror and single-pixel bolometer, as a prototype for a 120-element focal-plane array still under development. With our most recent version of the optical system, high quality images, with clear detail on a spatial scale of 1 cm, have been obtained with acquisition times of 70 s and a target range of 1.3 m.
