Abstract
This paper describes the results of ultrasonic goniometry measurement in Aquilaria (gaharu) wood. Ultrasonic wave was transmitted into the surface of gaharu wood and the reflected amplitudes by corner reflection were measured. The measurements were performed on gaharu sample with dimension of about 3mm x 15mm x 25mm by attaching to corner reflector goniometer made of mild steel. The measurement results are explained and discussed.
Keywords: ultrasonic, goniometry, gaharu.
