| Abstract: | This paper proposes a method which utilizes the same three structural modules of laser triangulation measurement in combination with three-synchronous driving technology.Additionally,this method improves the measurement accuracy by ensuring synchronization between thickness-data obtained by the upper and lower laser triangulation modules and compensated thickness-data from the third one.Finally,this paper uses the method of statistical limit superior and limit inferior to analyze convergence of the measurem... |
