A new pulsed-OSL stimulation unit capable of producing stimulation pulses down to 4 us wide has been developed. A matrix of 49 light emitting diodes (LEDs) are pulsed using a voltage-to-frequency converter, which produces fixed width pulses of adjustable duty cycle in the frequency range 0-10 kHz. Since the average light power falling on a sample is proportional to the repetition rate of the pulses, we have used voltage control of the frequency to undertake linearly modulated optically stimulated luminescence (LM-OSL) measurements. The frequency modulated OSL signals from various phosphors relevant to dating and retrospective dosimetry have been investigated using the new unit. (C) 2001 Elsevier Science B.V.

LM-OSL from single grains of quartz: A preliminary study Bulur, Enver; SOLONGO, S; Bøtter-Jensen, L.; Murray, A.S. (2002-01-01) The recently developed single grain attachment for the Riso TL-OSL reader has been modified to achieve linearly modulated optically stimulated luminescence (LM-OSL). Three different types of luminescence behaviour were observed in 81 quartz grains measured. These types are those showing only the easy-to-bleach component, those with only the hard-to-bleach component, and those exhibiting all components. The results of this preliminary study show that LM-OSL experiments carried out at the single grain level m...
Advances in luminescence instrument systems Bøtter-Jensen, L.; Bulur, Enver; Duller, G.A.T.; Murray, A.S. (2000-12-15) We report on recent advances in the development of luminescence measurement systems and techniques at Riso. These include: (1) optical stimulation units based on new-generation powerful blue light (470 nm) emitting diodes providing up to 28 mW/cm(2) for OSL measurements; (2) an infrared (830 nm) laser diode unit providing up to 400 mW/cm(2) for stimulation of feldspars; and finally (3) an optical stimulation attachment based on a focused solid stale green (532 nm) laser for rapid OSL measurements of individ...
Optically stimulated luminescence from quartz measured using the linear modulation technique Bulur, Enver; Murray, A.S. (2000-12-15) The optically stimulated luminescence (OSL) from heated natural quartz has been investigated using the linear modulation technique (LMT), in which the excitation light intensity is increased linearly during stimulation. In contrast to conventional stimulation, which usually produces a monotonically decreasing signal, linearly increasing the stimulation power gives peaks in the signal as a function of time. In cases where the OSL signal contains more than one component, the linear increase in power of the st...
Locomotion Gait Optimization For Modular Robots; Coevolving Morphology and Control Pouya, Soha; Aydın Göl, Ebru; Moeckel, Rico; Ijspeert, Auke Jan (2011-01-01) This study aims at providing a control-learning framework capable of generating optimal locomotion patterns for the modular robots. The key ideas are firstly to provide a generic control structure that can be well-adapted for the different morphologies and secondly to exploit and coevolve both morphology and control aspects. A generic framework combining robot morphology, control and environment and on the top of them optimization and evolutionary algorithms are presented. The details of the components and ...
Design and construction of an automated OSL reader with open source software and hardware MARABA, Diren; Bulur, Enver (2017-11-01) 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 coun...
