THE FRONTIERS OF SMART MONITORING TECHNOLOGY

摘要

In order to maintain sustainability of those infrastructures in which have significant influence to social lifelines,an economical and rational maintenance management should be carry out to evaluate their life cycle cost(LCC).In this paper,the field application of optical base sensor technology,i.e.,Laser scanner,LDV,optical wave,thermography,stick scanner,CCD camera,Satellite portrait,Electromagnetic wave diagnostic,X-ray,are introduced and compared.The field-applicability problems(solution,accuracy,speedy and safety)were summarized and discussed.
