Design of Radiation Dose Reader Based on Area Array OSL Optical Fiber Dosimeters

Radiation dose reader based on area array optical stimulated luminescence( OSL) optical fiber dosimeters is used to measure the dose distribution of radiation field. The 5 × 5 area array OSL optical fiber dosimeters were developed by using Al2 O3: C crystals as radiation detectors. The dose data of radiation field were obtained by the point by point scanning method after exposed to X rays,and the performance of the system was evaluated preliminarily. This paper mainly introduces the principle of the system and the composition of the hardware circuit and the software programming.
