條紋投影技術於三維形貌、移動速度、與三維形變量量測的應用

Novel Anti-influenza Virus Agents

利用條紋投影（fringe projection）技術進行物體表面的三維形貌量測，是十分普遍的作法，本文除了介紹其量測原理，亦藉由公式推導，證明此技術亦可進行待測物各局部區域的三維速度、及三維形變量量測，甚至與形變有關的量測，例如三維熱膨脹系數、物表溫度分佈、表面駐波的分佈等，都可透過這項技術完成。在目前眾多形貌檢測技術中，是唯一一種僅由一張擷取影像，即可達到上述多項功能的光學檢測技術。 Profile measurements performed by fringe projection techniques have been commonly studied for a while. In this article, we extent its applications to the fi elds of velocity sensing and deformation inspection. Advantages of the proposed method include:(1) capacity of non-scanning and full-field measurements,(2) system simplicity,(3) fast measurement speed,(4) easiness for calibration, and(5) low environmental vulnerability(a major problem for interferometers) . Only one-shot measurement is required for data processing. The full-fi eld property makes it possible to inspect several objects at the same time.
