  • Patent number: 10962659
    Abstract: A process for manufacturing an optical system includes forming a first hydrophobic surface at a semiconductor substrate, providing a first drop of transparent material having a first shape on the first hydrophobic surface, and allowing the first drop to harden to form a first optical element having the first shape. The optical system may be a particle detector, and the process may optionally further include forming a light source at the semiconductor substrate configured to generate a light beam that passes through the first optical element and a cavity to a photodetector.

  • Publication number: 20210003721
    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.
