Abstract
The method of phase demodulation for wood grain orientation measurement has been improved by employing a laser sampling system instead of a laser scanning system and using an edge detection algorithm rather than an intensity detection algorithm. The laser sampling system is able to determine the average grain angle and estimate the wood defect distribution much faster and more accurate than the laser scanning system. The edge detection algorithm is able to transform not only an oriented laser pattern but also an oriented wood texture into a periodic histogram. For the hardwoods with weak tracheid effect but the texture direction indicative of the grain orientation, the orientation measurement of laser pattern can be replaced by the orientation measurement of wood texture.
