Abstract: A detection system and method using multiple detector arrays for single or multi-frequency imaging of an object or scene. A polarizing beam element can be arranged to pass or reflect radiation to first and second detector blocks of the detection system.

Abstract: A detection system and method using multiple detector arrays for single or multi-frequency imaging of an object or scene, with one or more channels arranged along perpendicular axes. A polarizing beam element can be arranged to pass or reflect radiation to first and second detector blocks of the detection system.

Abstract: A high-frequency detection system (100) such as a terahertz camera is disclosed which includes a first detector array (102), a second detector array (104), and a polarizing plate (106). The polarizing plate is interposed between the detector arrays such that it passes and/or reflects radiation signals (110) from a source (108) to the detector arrays. A first radiation signal (112) having a first polarization is passed through the polarizing plate to the first detector array, and a second radiation signal (114) having a second polarization is reflected from the polarizing plate to the second detector array. Both radiation signals are from source (108), which can be one or more human beings emitting radiation towards the detection system. In some embodiments, the detector arrays (102, (104) may be joined.
