近年來，光刺激發光劑量計(Optical Stimulated Luminescence Dosimeter, OSLD)逐漸在國外成為評估輻射劑量 的重要工具，其相較於目前使用頻繁的熱發光劑量計(Thermoluminescence Dosimeter, TLD)而言，具有單次照射後 可重複計測的優點(TLD 僅能計讀一次)；但礙於商業化之OSLD 目前僅做為人員劑量佩章及皮膚劑量計等用途， 其體積太大而無法放置於侖道假體(Rando phantom)內進行體內器官劑量測量。目前雖可取得體積較小的OSLD 材 料，但卻無商業化之計讀儀可進行計測，因此本研究依據OSLD 之原理與特性及研究需求並參考相關國際文獻自 行設計與製作一OSLD 計讀儀，並針對此自製之計讀儀進行測試與分析。

In recent years, optically stimulated luminescence dosimeter (OSLD) has become a crucial tool for assessing radiation doses. In contrast to the commonly used thermoluminescence dosimeter (TLD), OSLD possesses the advantage of repeated readouts following a single radiation exposure (TLD only allows a single read). However, commercialized OSLD can only be used as personnel dosimeter badges and skin dosimeter and cannot be placed in Rando phantoms to measure internal organ doses because of its large size. Currently, relatively small-sized OSLD materials can be obtained, but commercialized readers for performing readouts are currently unavailable. Thus, based on principles and characteristics of OSLD and relevant international literature, this study endeavors to design and develop a reader for OSLD and perform various calibration tests and analyses on the self-made reader.
