Based on the analysis of infrared detection technology and Lambert-Beer law a new kind of quad-channel non-dispersive infrared (NDIR) gas concentration analyzer is designed by applying the modulated IR light source and a quad thermopile sensor into automobile exhaust gases concentration detection. The emphasis is paid on the analysis of modulated light source, gas chamber, sensor and the acquisition and processing circuit of the signal. The result of simulation and analysis of the designed circuit proved the feasibility of the design.

The Moment

With the continuous development of football games, more and more football matches are hold in the world. From the World Cup to the big league, the erroneous decisions of the goals by referee always became the focus of the games. Federation International de Football Association (FIFA) is discussing now to introduce high technology to the football games to assist the judgment of the referee. In this paper, an advanced detection technology for soccer goal is proposed. This goal detection technology is based on the optical principle, high speed camera, as long as infrared detection devices. By detecting the change of electronic signal in the moment of goal, which can cut off the laser beam, the goal can be detected. In addition, the detection results and in-situ video are transmitted in real time to the arbitrators, which can reduce the goal disputes and make the game of football more fair.

Near-infrared fl uorescence immunoassay has been widely studied in the bio analytical fi eld. This review mainly introduces the basic principles of near-infrared spectroscopy and near-infrared detection technology, and summarizes the properties, characteristics and recent improvement of optical properties and signal intensity of three near-infrared fl uorescence probes (i.e. organic fl uorophores, quantum dots and rare earth compounds). We describe the applications of near-infrared fl uorescence technology in immunoassay, and prospect the application potential of lateral fl ow assay (LFA) based on this probe in the rapid detection of pathogens. Our team intends to establish a new platform which has highly sensitive near-infrared fl uorescence probes (NIFPs) combined with portable and simple immunochromatographic test strips (ICTSs) for rapid detection of food borne viruses. This will provide technical support for a rapid detection on the port.

Water rush and mud rush are two major problems during the process of tunnel construction, which can lead to big troubles. Advanced geological prediction should be carried out to prevent the emergency of water rush and mud rush during the construction in the karst and water-rich areas. Infrared detection technology is a way to detect the hidden water. In this paper, basic principles of model HY-304 infrared detection meter are described, and it is applied in Shuangbei Tunnel. By analyzing the predicted results and comparing it with the situation of excavation, the instrument is feasible as to water rush in karst areas and infrared detection technology has a great opportunity to be applied in the tunnel engineering under complex geological conditions.

Detection Technology

This paper aims to explore the current status, research trends and hotspots related to the field of infrared detection technology through bibliometric analysis and visualization techniques based on the Science Citation Index Expanded (SCIE) and Social Sciences Citation Index (SSCI) articles published between 1990 and 2018 using the VOSviewer and Citespace software tools. Based on our analysis, we first present the spatiotemporal distribution of the literature related to infrared detection technology, including annual publications, origin country/region, main research organization, and source publications. Then, we report the main subject categories involved in infrared detection technology. Furthermore, we adopt literature cocitation, author cocitation, keyword co-occurrence and timeline visualization analyses to visually explore the research fronts and trends, and present the evolution of infrared detection technology research. The results show that China, the USA and Italy are the three most active countries in infrared detection technology research and that the Centre National de la Recherche Scientifique has the largest number of publications among related organizations. The most prominent research hotspots in the past five years are vibration thermal imaging, pulse thermal imaging, photonic crystals, skin temperature, remote sensing technology, and detection of delamination defects in concrete. The trend of future research on infrared detection technology is from qualitative to quantitative research development, engineering application research and infrared detection technology combined with other detection techniques. The proposed approach based on the scientific knowledge graph analysis can be used to establish reference information and a research basis for application and development of methods in the domain of infrared detection technology studies.
