WOOD DIFFERENTIATING SYSTEM

摘要

A wood differentiating system comprising a line-forming laser, a camera and a computer is described herein. The line-forming laser projects a line of laser light onto wood lumber and the camera takes a picture of the illuminated area of the wood lumber. By determining the width of the scattered light in the fibres of the wood lumber, the computer is capable of differentiating between lumbers made of fir and lumbers made of spruce, for example.
