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.

This design uses the pyroelectric infrared detection technology, single-chip microcomputer control. Pyroelectric infrared sensor sensing the infrared thermal radiation (the body temperature is 37 degrees) of the invaders, converting it into a low frequency signal, passing to microcontroller through amplified circuit. Finally, it implements anti-theft through the alarm module.

Application Potential

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.
