摘要

The ability of polycapillary optics to reject radiation incident outside the critical angle for total external reflection while efficiently transmitting radiation within the critical angle make them ideal two-dimensional angular filters for X-rays and neutrons. The use of such angular filters is shown to be important for medical imaging to give contrast and resolution improvement, for improved spatial resolution and contrast for radiological imaging, as two-dimensional collimators for diffraction measurements, for X-ray source size and shape measurements, and for x-ray and neutron angular distribution measurements.
