In the recent years, millimetre wave and THz imaging have received a vast amount of interest due to the interesting possibilities and applications that imaging at these frequencies could enable. Many of the applications that have generated substantial interest (such as stand-off concealed weapons detection) often require exquisite sensitivity, while a low(More)
We describe a broadband terahertz camera based on a modular 64-element linear array of superconducting hot-spot microbolometers. Unlike many superconducting sensor arrays, the readout for this array is performed entirely by uncooled electronics; no SQUIDs or cryogenic HEMTs are employed. The operating principles for the microbolometer and the readout scheme(More)
