Özet

An Optically Stimulated Luminescence (OSL) reader accompanying a sample changer unit for multi sample measurements was designed and constructed so that consecutive automated luminescence measurements can be performed. The reader was realized using open source software and hardware to minimize the development costs. The core control system of the reader is an open source single-board microcontroller (Arduino DUE). The control of sample positioning mechanism, stimulation system, precise timing and photon counting are accomplished using entirely this board. A user friendly measurement control software was written in an open-source programming language (Python) so that it can be run on any platform. The stimulation system utilizes a high power light emitting diode in the visible region and was designed to enable the commonly used stimulation modes known as continuous wave and linearly modulated OSL. The system went through operation testing with materials commonly used for dosimetry and dating studies and showed that it is precise for luminescence measurement. (C) 2017 Elsevier Ltd.
