There is provided an object scanning apparatus. The object scanning apparatus may include a THz source emitting a THz beam; an optical system for directing the THz beam; a zone for inspecting objects wherein the optical beam interacts with the object; a motion device for changing the spatial or temporal interaction of the object and optical beam; at least one transducer, the at least one transducer including an imaging transducer for converting the optical beam energy after interaction with the object to an electronic image; and a processor for performing processing of the image for use in characterization of the object or its interior contents or composition.

Techniques for dynamic object detection

Target devices for characterizing terahertz imaging systems are provided. The target devices include a terahertz resolution pattern having spatially distributed resolution features and one or more prism assemblies configured to provide a variable contrast level within the resolution features when used with terahertz radiation. Each prism assembly includes first and second prisms arranged in a Frustrated Total Internal Reflection (FTIR) configuration.
