The fθ lens is constituted by a first lens, which is a spherical lens having a positive power, a second lens, which is a spherical lens having a negative power, a third lens, which is a spherical lens having a negative power, a fourth lens, which is a spherical lens having a positive power or a negative power, and a fifth lens, which is a spherical lens having a positive power, provided in this order from the side of the galvanometer mirror. The scanning optical system satisfies Conditional Formula (1) below: | 03-05-2015 |
20150309191 | Downhole Gas-Filled Radiation Detector with Optical Fiber - Systems and devices are provided that relate to a gas-filled radiation detector with an internal optical fiber. The internal optical fiber may detect photons emitted during ionization avalanche events triggered by incident radiation. Such a radiation detector may include a housing, a fill gas within the housing, and an optical fiber within the housing. The fill gas may interact with radiation through an ionization avalanche that produces light. The optical fiber within the housing may capture the light and transmit the light out of the housing. | 10-29-2015 |
20150378033 | Scintillation Detector - The invention relates to X-ray imaging devices, particularly to devices for X-ray mammography and tomosynthesis. The scintillation detector comprises at least one photosensor with an array of cells each of thereof has a photosensitive area, and a scintillator arranged in the form of a structured aggregate made of elements isolated from each other and placed on the surface of the photosensor. The new construction of the proposed scintillation detector is the completely eliminated need for precise alignment of the structured scintillator based on the elements with a matrix of cells of a photosensor. Precise arrangement of the scintillation elements and the matrix of cells of a photosensor is performed directly during the formation of the scintillation elements. The technical result achieved by using the invention is the increase of image contrast. | 12-31-2015 |
