Abstract
A passive mm-wave imager comprises an optical immersion lens arrangement which is illuminated by front end optics and an array of detectors (12a) to (12d) located in the focal plane of the immersion lens arrangement. The detectors comprise antennae coupled high temperature superconductor weak links, in particular C-axis cross-over or step microbridges.
