ABSTRACT:
This invention provides a radiation directing device, including a screen having a mirrored surface interrupted by one or more pin holes that pass through the screen, the pin holes having an elliptical shape. The invention further provides an apparatus, including (a) a screen having a mirrored surface interrupted by one or more pin holes passing through the screen; and (b) a detector for detecting radiation reflected by the mirrored surface, wherein the detector determines a position of a radiation beam relative to the pin hole.
