【Abstract】 Based on coded aperture technology, a new method for forward scattering imaging is presented. The intensity of the forward scattered photons can reveal the information of the density. Combined with dual-energy technologies, which can obtain the information of the effective atomic number (Zeff) of an irradiated object, contrabands such as explosives can be discovered. By using the MCNP code, an simulation is conducted, and the result is promising.更多还原
