Scanning system for wood

A scanning system to analyze wood and determine defects, the scanning system comprising:

• at least two ultrasonic transducers configured to scan the wood from edge to edge by triangulating the wood, wherein said at least two ultrasonic transducers are configured to find splits and shakes, wherein said at least two ultrasonic transducers are configured to determine a best edge and/or to confirm a hole by making sure of a true open area, wherein said at least two ultrasonic transducers comprise at least one pulsar and a corresponding at least one receiver, each said pulsar and the corresponding receiver being oriented at a same angle relative to a side of the wood, wherein each said pulsar injects sound into the wood on one side while the corresponding receiver on the other side of the wood records all escaping sound;
• a floating head attached to a supporting member configured to move freely in a perpendicular direction to the wood, said floating head having an angled front at a front end of the floating head configured for contacting the wood allowing the wood to move the floating head up and down;
• said at least two ultrasonic transducers being affixed to the floating head at a position configured to maintain an air gap between a top edge of the wood and the at least two ultrasonic transducers;
• wherein, when the wood is moved under the floating head, said floating head moves freely up and down, whereby said at least two ultrasonic transducers maintaining the air gap between said ultrasonic transducers and the wood.
