Abstract

The invention discloses a neutron ghost imager. The ghost imager comprises a neutron source, a magnet structure, least one neutron sensor, and imaging devices. The neutron source is used for generating a neutron beam. The magnet structure is arranged towards the emission direction of the neutron beam, and is used for spatially modulating the neutron beam and irradiating the modulated neutron beamto the surface of a to-be-imaged object. The neutron sensor is arranged in parallel with the to-be-imaged object, and is used for receiving a neutron beam passing through the to-be-imaged object. Theimaging devices are respectively connected with the magnet structure and the neutron sensor, and are used for reconstructing the to-be-imaged object according to the received neutron beam and a magnetic polarization direction distribution function at irradiation of the received neutron beam in the magnet structure, or reconstructing the to-be-imaged object according to the received neutron beam and the magnetic polarization direction distribution function of the neutron beam after spatial modulation. According to the neutron ghost imager, the purpose of the invention can be achieved with onlyone or more neutron sensors and without focusing imaging on the neutron beam and a neutron sensor array; and the structure is simple, the size is small, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a neutron ghost imager. Background technique [0002] Neutrons have high penetrability, and neutrons have a strong magnetic moment, which is especially suitable for crack detection in high-density and magnetic materials, material performance analysis and other fields, and can well make up for other non-destructive testing such as X-rays. Inadequacy of the method. [0003] However, since neutrons do not carry charges, it is difficult to focus neutrons; and because of their strong penetrating ability, generally speaking, neutron detectors are relatively large, and it is difficult to integrate them with traditional optical imaging components CCD (Charge Coupled Device, charge-coupled device), CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor) are highly integrated, imaging is difficult and the imaging quality is not high, which seriously ...
