Backscatter characterization using interlinearly adaptive electromagnetic X-ray scanning

Methods and an x-ray source for sweeping an x-ray beam across an object of inspection. A beam of electrons is emitted by a cathode, while a sweep controller applies a signal to a beam controller in a prescribed path on an anode, thereby causing an x-ray beam to be emitted from an aperture disposed at one apex of a snout of variable length. The aperture may be a Rommel aperture that allows for forming a scanning x-ray of desired size and flux independently of the angle at which the beam is emitted. Scanning rate may be varied during the course of a scan. Multiple x-ray beams may be formed simultaneously, where one beam is inside a conveyance while the other is outside the conveyance, for example.

MULTI-STATIC AND BISTATIC COHERENT LIDAR WITH LASERS LOCKED TO A REFERENCE

A system and method for a bistatic coherent LIDAR system with lasers locked to a reference. Utilizing atomic absorption lines to lock the frequency for the bistatic system provides an absolute reference, as each of the lasers in the bistatic system would have the same frequency to within the linewidth of the frequency reference. Each laser may also be additionally locked to an optical cavity for increased frequency stability. Not only does such a system provide essentially an infinite aperture, it also reduces laser power requirements because the detector platforms could be much closer to the target than the platform that contains the laser.
