Nuclear detection device

Abstract

The invention discloses a nuclear detection device which comprises a flicker unit, a micro-optics unit, a photovoltaic conversion device and an image collecting and data processing unit, wherein the flicker unit is made of organic or inorganic crystals or thin film materials and is used for converting incidence beams into flicker light, and the converted flicker light is radiated to the micro-optics unit; a unit lens is used for generating a unit image of an object and the image is received by the photovoltaic conversion device; the photovoltaic conversion device is used for converting the received unit image into a two-dimensional data electric signal and transmitting the unit image to the image collecting and data processing unit; and the image collecting and data processing unit is used for acquiring, storing and processing the two-dimensional data electric signal obtained by the photovoltaic conversion device, and carrying out data reconstruction according to an optical path structure of the device so as to obtain the position that a photon is generated in the flicker unit. With the adoption of the device, the requirements on the flicker materials are reduced, the three-dimensional information about the position that the flicker light is generated in the flicker materials is obtained directly, the position identification can be realized and at the same time energy identification ability is provided, so that the performance of the nuclear detection device is improved.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a nuclear detection device. Background technique [0002] At present, nuclear detectors are key components for ray detection in the research fields of high-energy physics and nuclear physics, and are widely used in military, industrial detection, and medical imaging. According to different functions, nuclear detectors can be divided into position-sensitive, energy-resolving, time-resolving, and detectors with multiple functions at the same time. Among them, the scintillation detector is a common technology in nuclear detectors. The scintillation material is a luminescent material used to detect and record various ray particles (including X-rays, γ-rays, and neutrons, etc.). When charged or uncharged particles pass through the scintillator, their energy is absorbed, which causes the molecules or atoms of these materials to be excited and ionized. When these excited mo...
