This paper discusses a new approach to X-ray non-intrusive (NDE) inspection based on hard X-ray imaging optics. A new X-ray lens, called lobster-eye-lens (LEL) is the transmission lens, based on reflection optics, with grazing-angle deflection of 0.2° and photon energy of 40-100 keV. The lens reflection-optics is based on large, high-quality X-ray mirrors with r.m.s. lower than 1 nm. The through-the-wall inspection capability of such a system, based on Compton back-scattering, can be applied for longer ranges, (up to 100 m in the air), and thick walls (over 2 cm for wood, and over 2 mm for metal). CONOPS examples are given for homeland security applications. |
