Problems solved by technology

So far, nuclear imaging technology is mainly used in the medical field and has achieved great results. Whether nuclear imaging technology can be used in the field of security and anti-counterfeiting is the background subject to be discussed in the present invention. No matter what kind of existing nuclear imaging technology , all through the tomographic scanning of the inspected object, and then applying computer technology to reconstruct the image to obtain the internal material analysis of the inspected object. As long as the same equipment, materials and technology are available, the same anti-counterfeiting product can be imitated. Therefore, it is impossible to achieve the anti-counterfeiting purpose of restraining others from forging

Embodiment Construction

[0022] The present invention is described in detail below in conjunction with accompanying drawing:

[0023] see figure 1 with figure 2 . There is a stage 2 in front of the support 1, and the center of the stage 2 is the center of a circle. An annular analysis disk 6 is installed, and a microscope lens 3 and a microscope lens 3 for observing the three-dimensional distribution image of the nuclear track are sequentially installed on the top of the stage 2. The camera 5 that converts it into digital information, in order to make the observed nuclear track clearly, is equipped with an illumination source 4 around the outer circumference of the microscope lens 3. The illumination source 4 can be composed of a light-emitting diode, or a cold light source can be used to pass through an optical fiber. leads to the periphery of the microscope head 3. The formation of nuclear tracks is as follows: First, take a solid nuclear track detector with a thickness of 2mm, such as CR39, and...

Abstract

The invention provides a nuclear imaging analyzer for detecting nuclear track double-card anti-counterfeiting marks, which is characterized in that: an analysis disk is set with the center of the stage as the center of a circle, and nuclear imaging technology is used as a guide to conduct three-dimensional distribution of nuclear track Tomography, so as to accurately identify the authenticity of the nuclear track carrier, is the necessary detection equipment for the nuclear track series products.

Description

Technical field [0001] The invention relates to a nuclear imaging analyzer for nuclear track detection, which belongs to the technical field of information processing in physics. technical background [0002] The traditional nuclear imaging technology originated from the transmission computer X-ray tomography invented by Hansfield, an engineer of the British EMI company, in 1972, followed by nuclear magnetic resonance imaging, Compton scattering imaging, positron imaging and Mössbauer imaging. Imaging and other nuclear imaging technologies have come out successively (see "Applied Nuclear Spectroscopy" published by China Science and Technology Press in May 1994 for details). So far, nuclear imaging technology is mainly used in the medical field and has achieved great results. Whether nuclear imaging technology can be used in the field of security and anti-counterfeiting is the background subject to be discussed in this invention. No matter what kind of existing nuclear imagin...
