Studies on Portable 3D Laser Scanner for Surface Flaws

Abstract

A portable 3D laser scanner based on laser triangular principles has been developed to increase the accuracy and reliability of surface flaw measurements. The instrument optically scans a 4×4 cm2 surface area in under 2 seconds. Resultant data can be sent to a laptop PC via Ethernet transmission. A program running on the PC detects and calculates the dimensions of the flaws, and displays a 3D image in real time during the scan.
