Abstract
A method of determining the presence and quantity of wood treatment substance (pesticides, water repellants, dimension stabilizers and the like) on wood is provided. The wood treatment substance is combined with a fluorescent material and applied to wood. A light beam is impinged on the wood, and reflected light measured by a spectral device. Color saturation level of the reflected light is determined with a microprocessor. From this measurement a quantity of wood treatment substance on the wood can then be determined.
Claims7
A method for detecting the quantity of wood treatment substance on wood comprising the steps of:
- impinging a light beam on wood having a wood treatment substance and fluorescent material thereon;
- detecting light reflected from said fluorescent material;
- converting detected light to a corresponding electrical signal;
- employing said electrical signal to determine the color saturation level of the light reflected from said fluorescent material;
- and
- determining a quantity of said wood treatment substance from said color saturation level.
