反射變換成像（Reflectance Transformation Imaging, RTI）是一項性能極佳的影像記錄與成像技術，此技術生成之影像擁有優異的辨識幾何紋理能力與畫面細緻度；非接觸式的影像收集模式可以在確保作業安全性的同時，記錄肉眼所無法辨識之物件表面細節；交互式照明的拍攝過程使RTI的生成影像於觀察軟體中擁有獨特的觀察方式，使一個觀察點可以呈現不同光線角度所照射的影像，從而使得觀察者可以進行更深入的研究，是RTI特有的優勢。本研究以文化資產保存的角度，以RTI為寺廟之石碑文物進行碑文的辨識，研究對象「月眉山靈泉禪寺置業碑記」是接近百年歷史的石碑，因受地理與氣候的環境因素影響，記載著寺廟修建沿革之碑文即將因嚴重的風化損害而變得模糊甚至無法辨識，為免重要的歷史訊繼續流失，應即刻為碑文之雕刻與內容進行記錄，以及利用RTI所獲得之「線索」補全無法閱讀之碑文。本研究成功為研究對象進行RTI的記錄，得以完整保存其表面的雕刻與細節，並於18個特定模糊碑文中辨識出13個單字。

Reflectance Transformation Imaging (RTI) is an exceptional imaging and recording technique. The images produced by this method exhibit excellent capabilities in distinguishing geometric textures and intricate details. Its non-contact image acquisition mode ensures operational safety while capturing surface details indistinguishable to the naked eye. The interactive lighting process in RTI offers a unique viewing method in its software, allowing an observation point to display images illuminated from various angles. This facilitates a more in-depth analysis, marking a distinct advantage of RTI. From the perspective of cultural heritage preservation, this study utilizes RTI to decipher inscriptions on temple stelae. The subject, "Yue Mei Shan Lingquan Zen Temple Establishment Stele," is a century-old monument. Due to geographical and climatic factors, the inscriptions, which chronicle the temple's construction history, are at risk of becoming illegible or entirely obscured due to severe weathering. To prevent further loss of this crucial historical information, it's imperative to document the stele's engravings and contents immediately and use RTI-derived "clues" to reconstruct unreadable inscriptions. This study successfully recorded the stele using RTI, preserving its surface engravings and details. Out of 18 specific blurred inscriptions, 13 words were identified.
