Popis:	This paper describes an effort for development of a thermal imaging equipment aboard a high speed vehicle to detect anomalous regions in concrete structures of road tunnels. This type of infrared equipment would be required for the use of tunnel safety inspection with no traffic regulations on real expressways. Presented in this paper are theoretical analyses of the detection capability for inner thermal anomalies in the concrete wall, discussions on applicability of infrared detectors and on optimum scanning schemes for the imaging system, and finally, results of design and prototyping of the equipment along with field data.
