N2 - The fiber optic X-ray sensor is an intensity-modulated fiber sensor suitable for precise radiotherapy. In practical applications, bending and twisting of the fiber probe may occur due to placement requirements, leading to signal light intensity attenuation. To address this issue, this paper proposes a compensation structure that utilizes inorganic scintillation materials' response to ultraviolet light. By coupling a UV LED light source to excite the scintillator on the transmission fiber and detecting the returned fluorescence intensity, the bending loss in the fiber can be determined. A compensation algorithm based on the ratio of fluorescence loss can calculate bending loss and perform radiation dose compensation, thereby improving the accuracy of dose measurements. Compared to other compensation measures, this self-compensating device has a simple structure and can achieve intensity self-compensation without increasing the volume of the fiber probe, providing convenience for effective radiation detection within patients.
