摘要
Pi CUS3是新型的应力波探测设备,通过测量声波传播速度,用于活立木的树干空洞的无损探测。本文在阐述Pi CUS探测原理的基础上,分析了探测树木空洞的具体流程与措施,对探测结果进行可视化显示。研究结果表明,使用Pi CUS设备可以在不损伤树木的状况下有效探测出树干是否存在空洞以及空洞的位置分布。
The PiCUS3 Sonic Tomograph is a new version unit can detect the cavities in standing trees non-invasive-ly by tracking the speed of sound waves in the trunk .Based on PiCUS detection principle ,the processing and measure-ments of detection were analyzed in this paper .The detection results were described visually .The research results show that the caves and their positions in the tree trunk can be detected effectively using the PiCUS equipment in non -inva-sively condition .
