Details of newly developed system for fracture surface contour measurement were described.A commercially available laser displacement meter based on the triangulation principle was ised as a main hardware in the firat system.Another laser displacement with higher resolution,which is based on the principle of critical angle,was utilized in the second system developed in the present study.An emphasis was put on the software development for widening a dynamic range of heigh measurement with keeping high resolution in both system, in order to find a frcture surfacezig-zag contour superposed on the log-range uundulation. Finally, the successful use of the contour measurement by these systems was demonstrated for the topographical analsis of the fracture surfaces of ductile and brittle fracture samples.
