Abstract: An integrated electronic device, delimited by a first surface and by a second surface and including: a body made of semiconductor material, formed inside which is at least one optoelectronic component chosen between a detector and an emitter; and an optical path which is at least in part of a guided type and extends between the first surface and the second surface, the optical path traversing the body. The optoelectronic component is optically coupled, through the optical path, to a first portion of free space and a second portion of free space, which are arranged, respectively, above and underneath the first and second surfaces.

Abstract: A device such as a dosimeter for detecting ionizing radiation, for example, X-ray radiation, in hospitals or the like. The device includes scintillator material configured to produce light as a result of radiation interacting with the scintillator material, and photoelectric conversion circuitry optically coupled to the scintillator material and configured to produce electrical signals via photoelectric conversion of light produced by the scintillator material. The device includes a plurality of photoelectric converters optically coupled with the scintillator material at spatially separated locations. The plurality of photoelectric converters thus produce respective electrical signals by photoelectric conversion of light produced by the scintillator material as a result of radiation interacting with the scintillator material. Improved energy linearity is thus facilitated while providing more efficient detection over the whole energy spectrum of radiation detected.
