Abstract :
We demonstrated terahertz imaging using a two-dimensional array detector with 5times5 elements based on superconducting tunnel junctions. Real-time 25-pixel imaging at 0.65 THz was successfully performed. The array detector also allowed the shortening of the total acquisition time for larger images, made up of pixel blocks.
