High-speed and large field-of-view imaging through terahertz focal plane arrays

By using plasmonic nanoantennas that can act as light concentrators in infrared band and terahertz antennas in terahertz band, we developed a terahertz focal-plane array (THz-FPA) that can be used in terahertz pulsed imaging systems. The detector array consists of 64 pixels and can scan a line width of 5 cm. By offering high scan speed with large field-of-view, the THz-FPA can transform terahertz pulsed imaging systems from a metrology tool to a high-throughput instrument that can be used in industrial settings for various non-destructive evaluation applications.
