Multipixel x ray detection integrated at the end of a narrow multicore fiber
Résumé
We introduce and demonstrate the concept of a multipixel detector
integrated at the tip of an individual multicore fiber. A pixel
consists here of an aluminum-coated polymer microtip incorporating
a scintillating powder. Upon irradiation, the luminescence released
by the scintillators is efficiently transferred into the fiber
cores owing to the specifically elongated metal-coated tips that
ensure efficient luminescence matching to the fiber modes. With
each pixel being selectively coupled to one of the cores of the
multicore optical fiber, the resulting fiber-integrated x ray
detection process is totally free from inter-pixel cross talk. Our
approach holds promise for fiber-integrated probes and cameras for
remote x and gamma ray analysis and imaging in hard-to-reach
environments.
