A Lobster Eye X-ray Imaging System based on a unique Lobster Eye (LE) structure, X-ray generator, scintillator-based detector and cooled CCD (or Intensified CCD) for real-time, safe, staring Compton backscatter X-ray detection of objects hidden under ground, in containers, behind walls, bulkheads etc. In contrast to existing scanning pencil beam systems, Lobster Eye X-Ray Imaging System's true focusing X-ray optics simultaneously acquire ballistic Compton backscattering photons (CBPs) from an entire scene irradiated by a wide-open cone beam from one or more X-ray generators. The Lobster Eye X-ray Imaging System collects (focuses) thousands of times more backscattered hard X-rays in the range from 40 to 120 keV (or wavelength λ=0.31 to 0.1 Å) than current backscatter imaging sensors (BISs), giving high sensitivity and signal-to-noise ratio (SNR) and penetration through ground, metal walls etc. The collection efficiency of Lobster Eye X-ray Imaging System is optimized to reduce emitted X-ray power and miniaturize the device. This device is especially advantageous for and satisfies requirements of X-ray-based inspection systems, namely, penetration of the X-rays through ground, metal and other material concealments; safety; and man-portability. The advanced technology disclosed herein is also applicable to medical diagnostics and military applications such as mine detection, security screening and a like.

A liquid crystal display is provided with a detection range on its screen. Along right and left sides of this detection range, two mirrors are arranged as opposed to each other, and along one of sides perpendicular to the sides along which the mirrors are arranged a camera unit is arranged. The camera unit comprises a linear light sensor and a pinhole. When an arbitrary position in the detection range is pointed by a fescue, the linear light sensor detects a real image of a detection target. The linear light sensor also detects a mapped image of the detection target reflected by the mirror. Then, positional information of the real image and the mapped image of the detection target on the linear light sensor is used to obtain a two-dimensional position of the fescue in the detection range.
