Abstract:
1. An apparatus for remotely examining contents of a container, the apparatus comprising: a laser source that produces a sub-picosecond laser pulse with at least a terawatt peak power; an adjustable support; an optical focusing element mounted on the adjustable support; a laser target positioned to receive the sub-picosecond laser pulse and mounted on the adjustable support; a laser wakefield beam of electrons that emerges from the laser target due to focusing the sub-picosecond laser pulse by the optical focusing element onto the laser target; wherein the adjustable support rotates about at least one axis of rotation and rotates the laser wakefield beam of electrons in a direction to examine contents of the container; a detector that detects a signal emitted from interaction between the laser wakefield beam of electrons and contents of the container.
