ABSTRACT:
A grid for use in a collimator system for high energy waves such as X-rays and gamma rays includes a silicon base in which slits are etched along multiple separated lines. Located transversely in the slits are tungsten slats. Between the separated lines, silicon is removed by etching. Pairs of grids are longitudinally spaced apart along a longitudinal axis running transversely to the direction of the lines and the slats. Rotating the pair of grids about the longitudinal axis, and providing a detector associated with each grid pair provides for metering high energy rays.
