In this paper a new approach to 3D Compton imaging is presented, based on a kind of finite element (FE) analysis. A window for X-ray incoherent scattering (or Compton scattering) attenuation coefficients is identified for breast cancer diagnosis, for

Non-invasive real-time detection and identification of high explosives and improvised explosive devices, illicit materials hidden inside suitcases, vehicles, containers or behind metal and non-metal walls become critically important for safety and se

In this paper, biologically-inspired optical imaging systems, including fish eye, bug eye, lobster eye, and RGB color vision, are discussed as new lensing systems for military and homeland security applications. This new area of interest includes UV,

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

The angular distribution of the inelastic scattering of photons at low energies (≤80 KeV) has been measured in organic material, soil, rocks, wood, steel sheet, and water. The measurements have been performed under air inside an X-ray shield cabine

Detecting and identifying organic and metallic targets at distances from 50 m to 100 m is difficult for hard X-ray detection devices, especially when targets (such as improvised explosive devices (IEDs)) are concealed behind metal (steel) and non-met

We propose a new imaging device for the long infrared spectral range, inspired by the natural eye of a lobster. Such a lobster-eye lens is composed of reflecting channels with a square cross section capable of wide angle of view and practically omni-

In this paper, we discuss hard x-ray optics, in general, and lobster-eye focusing optics, in particular, for concealed object detection, at longer distances. The longer distance (~50m) scenario is important for Improvised Explosives Detection (IED),

A new approach to hard X-ray imaging is proposed, based on staring optics consisting of a lobster-eye lens. This new Staring Imaging Lobster-Eye X-Ray approach is especially suited to X-ray lobster-eye imaging of non-astronomical objects at finite di
