System for detecting X-rays at grazing incidence and an essentially rectangular detector cluster included in this system

摘要

The system is positioned in such a way as to intercept the radiated energy from the source 10 after passing through the object under examination 18. A number of elongated tubular elements 21 are arranged alongside and parallel to each other and lie in a direction roughly parallel to that of the linear scanning. Each element has an internal surface which reflects optical photons. A light-sensitive system produces a composite output signal representative of the energy content of the radiation from the object under examination. Application to an X-ray detector giving as short as possible an exposure time for the object under examination. IMAGE
