    摘要: A passive phased array imager includes a plurality of antennas, disposed on a substrate, for receiving a wavefront from a target; and a coplanar waveguide, disposed in the substrate and coupled to the plurality of antennas. Also included is a plurality of detectors, disposed across the coplanar waveguide for sampling the received wavefront, and providing multiple output voltages to an imaging circuit for displaying information contained in the received wavefront. The plurality of antennas includes at least two dipoles coupled to the coplanar waveguide, and the two dipoles are spaced by a predetermined length to provide a standing wave at a frequency of interest.

    摘要: A monolithic focal plane array (FPA) of an imaging system includes an array of multiple pixel unit cells disposed on a substrate. Each pixel unit cell includes: a first array of THz antennae disposed on a top layer of the substrate, and a second array of context imaging pixels disposed on the top layer of the substrate. The first and second arrays are interleaved on the top layer of the substrate. In addition, each THz antenna in the first array is shaped either in a bow-tie, circular or tuned waveguide configuration, and each context imaging pixel in the second array is shaped in a circular, or rectangular configuration.

    摘要: A focal plane array (FPA) imaging sensor includes an array of multiple tuning cells disposed on a monolithic substrate, in which each tuning cell includes: (a) a tunable etalon disposed in the monolithic substrate, and (b) a THz detector assembly comprised of at least two antennae disposed in the monolithic substrate. The THz detector assembly is disposed below the tunable etalon. Each tunable etalon includes a Fabry-Pérot interferometer comprised of upper and lower mirrors, spaced by a gap between the mirrors, the gap forming an etalon of the interferometer. The FPA imaging sensor may also be formed as a hybrid, in which portions of the tuning cells are fabricated separately from the THz detector assembly and aligned to each other. The lower mirrors may also be fabricated monolithically with the substrate and the upper mirrors may be formed separately and then aligned to the lower mirrors.
