The system applied to objects thickness measurement, the measurement results of real objects and the thickness of between unanimously that the more the possibility of Measurement ; On the other hand, the system provides another kind of scientific measurement Chinese medicine Pulse way,May observe on the pulse the skin slight to beat the situation, and accurately measuring changes in its amplitude and frequency, frequency of measurement error is less than 2.5 percent. en_US DC.subject 三角量測 zh_TW DC.subject 厚度量測 zh_TW DC.subject 中醫脈象 zh_TW DC.subject thic en_US DC.subject triangle measurement en_US DC.subject Chinese medicine Pulse en_US DC.title 新光學三角量測系統與應用 zh_TW dc.language.iso zh-TW zh-TW DC.title New optical triangle measurement system and application en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
