Abstract
We discuss about a fully-staring THz video camera prototype intended for security screening. The camera utilizes so-called kinetic inductance bolometers to detect THz radiation in the bandwidth of 0.3-1 THz. The imaging distance is 2.5 m with the nominal field-of-view of 2 m × 1 m. The camera is equipped with a kilo-pixel detector array, intermediate-scale cryogenics operating at 6 K, and low-noise electronics to read out the whole detector array. Here, we focus on describing the wide field-of-view and close-looking optical system of the imager.
