Explosive detection method based on portable mobile phone microscope

Abstract

The invention discloses an explosive detection method based on a portable mobile phone microscope. A detection device involved in the method is composed of a mobile phone supporting platform, a firstrotary knob, a first connecting rod, a gasket, a second connecting rod, a second rotary knob, a third connecting rod, an imaging hole, a microscope eyepiece, a lens cone, a microscope objective and anobjective table. After the mobile phone microscope is amplified by one hundred times, the resolution ratio of the mobile phone microscope can reach the micron level, the imaging quality can be comparable to that of a common optical microscope, the view field can reach 1800 microns, and the characteristics of high image resolution ratio and large view field are achieved. During actual explosive detection, hydrogel soaked with a detection reagent is adopted for sampling, the color change of a micro area on the hydrogel is observed through the mobile phone microscope, the mobile phone photographing and camera shooting functions are adopted, the purpose of detecting and recognizing explosive particles in real time in a visual mode is achieved, and therefore the sensitivity and portability ofon-site explosive detection are remarkably improved. The method has the advantages of being small in size, light in weight, convenient to carry, free of professional training and the like. An effective technical means is provided for on-site explosive detection and analysis of a public security system.

Description

technical field [0001] The invention belongs to the field of explosive detection and relates to a method for detecting explosives using a portable mobile phone microscope. Background technique [0002] In recent years, the number of explosive terrorist incidents has gradually increased around the world, and there is an urgent need for rapid and convenient detection and analysis technology for explosives, especially at security inspection sites such as railway stations and airports, where high requirements are placed on the portability of detection equipment and the convenience of detection methods. Currently commercialized detection methods include ion mobility spectrometry, portable Raman technology, and X and γ-ray detection methods. X-rays can only detect the density and effective atomic number of an object, but cannot distinguish its chemical composition. Ion mobility spectrometry and portable Raman technology Man technology can identify explosive components, but ion mob...
