MICROSTRUCTURE FOR SELECTIVE TRANSMISSION OF RADIATION

The invention relates to a microstructure (10) for selective transmission of radiation, such as a microstructure included in an imaging component for X-ray or gamma-ray imaging. The microstructure (10) comprises a first module (11) and a second module (12). Each of the modules (11, 12) comprises a grid of walls (20), with a first subset of the walls having a longitudinal axis extending in a first direction (x), and a second subset of the walls having a longitudinal axis extending in a second direction (y) transverse to the first direction (x). The walls (20) have a height axis extending in a third direction (z) transverse to the first (x) and the second (y) directions. The first module comprises a first partial interface wall (21), and the second module comprises a second partial interface wall (22). The first module and the second module have been tiled together such that the first partial interface wall (21) and the second partial interface wall (22) combine to form a common interface wall (23) at an interface between the modules, the common interface wall (23) having a longitudinal axis in the first (x) or the second (y) direction, and a height axis in the third direction (z).
