ULTRACLAWS SF0053 system is an ultrasonic-based scanning system for evaluation of gaharu volume in standing Aquilaria tree. The system specifically applied for all Aquilaria species which comprise different sizes and ages. It utilizes ultrasonic pulse by imparting the pulse to the wood using an ultrasound device which consists of at least a pair of opposed ultrasonic transducers to measure sound velocity in standing tree. The ultrasonic pulse passes from the transmitter through the trunk of the receivers by direct through transmission ultrasonic technique. Gaharu production is triggered by the inoculation technique where after five years of age the tree is injected with spores. This inoculation process is carried out for a period of 1 to 2 years before the gaharu is produced by the tree and harvested. The challenges are to come up with high quality, the desired grades and predictable volumes of the gaharu formation. However, there is no reliable or scientific technique that can predict or estimate the volume of gaharu produced inside the trunk before it is harvested. ULTRACLAWS SF0053 is equipped with 12 elements of exponential horn type ultrasonic transducers. By using multichannel ultrasonic pulse-receiver, this scanner has the ability to generate 2D slice image of gaharu truck. The system is able to estimate the quantity of generated gaharu by giving out the cross section image of the Aquilaria tree. It is hoped that this newly developed system can give benefits to the gaharu industry in Malaysia and the predictable volumes of gaharu before it can be harvested.
