Abstract
We present passive indoor imagery of human subjects in the 100 - 1000 GHz band. In order to obtain adequate ensitivity, a cryogenically cooled (4 K), broadband antenna-coupled, superconducting microbolometer with optical noise equivalent power NEP < 2 pW/rtHz was used as the sensor. Mechanical scanning of the collecting aperture, a 30 cm diameter spherical mirror, was used to slowly accumulate the images. While not yet practical for deployable real-time cameras, this system provides valuable phenomenological comparisons with similar imagery obtained with actively illuminated systems.Proceedings Title
