Abstract: The present disclosure relates to light isolating arrays (can also be called “light pipes” or “light pipe arrays”) that enable high transmission efficiency and isolation of light from one location, for example a lens, to another location, for example an array of photodetector diodes (each a “PD”). The light isolating arrays can provide optical isolation of the input light and can eliminate cross talk thus enhancing the resolution via increased contrast of the incoming signal. The light isolating arrays can also protect the PD's from contamination when used in outdoor devices.

Abstract: A shielding mesh to counter scattered ionizing radiation is provided. The shielding mesh includes a plate, arrangement of depressions, a mesh of trenches, and an x-ray-absorbing material. The plate has a first side and a second side opposite the first side. The arrangement of depressions are in the plate and are open toward the second side. The mesh of trenches are in the plate and are open toward the first side. The x-ray-absorbing material is in the mesh of trenches. The mesh of trenches and arrangement of depressions are configured so that a wall of the plate remains between the arrangement of depressions and the mesh of trenches.
