| 2008 Wenchuan earthquake, the lives of the application of advanced infrared detectors to search for trapped people. This was also remembered. This article from the latest infrared technology designed to detect life-infrared instrument.In this paper, the design life of the infrared detector optical system, scanning agencies, detectors, the signal processing, electronic circuits, display six parts. The main design elements are as follows:1 .An optical system are obtained by calculating the required part of the lens aperture, the radius of curvature, and the focal length, and designed the optical system structure diagram.2.Detectors in part through the work of band calculation, select the corresponding detector. Select a cooling mode and cooling liquid.3.Scan of part of the on-line scan and frame scan has been designed, respectively, and scanning carried out in detail.4.Part of the amplifier circuit has been designed, analyzed the detector readout circuit, choose the power battery, finally drawing the overall circuit diagram.5.Part of the signal transmission signal processing approach to the design.6.The final adoption of a comparison of various display, select the corresponding display system. |
