Abstract
The standalone, portable Terahertz (THz) Imaging Profiler Array (TIPA) based on an Offner Relay design has been constructed as a THz beam profiler and multispectral imager. It integrates a solid-state detector technology (Schottky Diodes) that can be configured in an array to cover the frequency range from 0.60 to 0.90 THz. The reconfigurable 16 element Schottky diode detector array is utilized along with imaging and scanning mirror modules and system control hardware and software to produce high spatial or temporal beam profiles of THz beams. Images of THz source profiles are presented along with THz images of relevant targets. Potential applications are discussed.
