The critical aspect of x-ray inspection in the security field often requires a customized solution to accomplish the mission whether on the field or in the lab.
To evaluate the threat of an unknown object in a particular location, a portable and fast scanning equipment is de rigueur. Additionally, the operator must be far enough from the potential danger, which implies that the system can be handled wirelessly. Since the acquisition speed is antagonist to image quality, a high resolution is not to be expected but the system should still be able to discriminate materials from different natures.
Other applications involve stationary systems and the need for high resolutions, high quality images. A relevant example is the detection of counterfeit money.
