Embodiment 1

[0015] In specific applications, such as figure 2 , First select 7 plastic optical fibers with the same parameters, and use physical methods to remove the outer cladding structure; insert the plastic optical fiber bundle 1-1 with the cladding removed into the plastic sleeve 1-2 with a lower refractive index than the fiber core material, and prepare Taper; taper the multi-core plastic optical fiber using the plastic optical fiber taper device, and make the core diameter of the single fiber port 1-3 after taper the same or similar to the core diameter of the white optical fiber; The other end of the bundle 1-1 is connected to the plastic scintillation fiber 2-1 as the input end of the optical signal, and the single fiber port 1-3 is connected to the white optical fiber 2-3 as the output end to couple and collect the energy of the optical signal; The white optical fiber 2-3 is connected with the photomultiplier tube 2-4 to collect data, and the information processing system 2-5 p...

Abstract

The invention discloses a clustered plastic fiber lantern which belongs to the field of astronomical photonics. The clustered plastic fiber lantern comprises a plastic fiber bundle, a plastic sleeve and a single fiber port. One end of the plastic fiber bundle is inserted into the plastic sleeve. The single fiber port is a single fiber which is formed through inserting the plastic fiber bundle intothe plastic sleeve and tapering by a plastic fiber tapering device. The plastic fiber bundle is composed of a plurality of plastic fibers with the same parameter. The refractive index of the plasticsleeve is lower than that of the plastic fiber. The diameter of the plastic fiber bundle is same with the internal diameter of the plastic sleeve. The diameter of the single fiber port is same with that of a white fiber. Compared with the prior art, the plastic fiber has advantages of high flexibility, high durability and low cost. Furthermore the clustered plastic fiber lantern satisfies requirements for spatial resolution and energy resolution and can be used for detecting an optical signal underwater.

Description

Technical field [0001] The invention belongs to the field of astronomical photonics, and particularly relates to a clustered plastic optical fiber lantern. Background technique [0002] Cosmic rays are a stream of high-energy particles from the depths of the universe. They are the only material carrier from cosmic space. They are mainly composed of bare atomic nuclei such as protons, helium nuclei, and iron nuclei, as well as some gamma rays and neutrinos. Scientists have successively developed sub-disciplines such as cosmic ray physics, gamma-ray astronomy, neutrino astronomy, and extremely high energy cosmic ray physics, and at the same time they have carried out antimatter and dark matter detection. For low-energy cosmic rays with large particle fluxes, nuclear electronics detectors such as balloons, satellites, and space stations can be directly observed in the outer space of the atmosphere. As for high-energy cosmic rays, due to the small particle flow and the small effecti...
