    Abstract

    A compact and lightweight computer-controlled system is described that allows for the measurement of optically stimulated luminescence of sediments in the field, whether in the form of loose grains or compressed pellets. The unit uses infrared OSL excitation, with highly efficient bleaching and OSL regeneration provided by cold-running gas discharge lamps. The modular form means that the mobile system can be built up into a full luminescence excitation/emission spectrometer useful in the wavelength range 380-1000 nm, thus allowing both quartz and feldspar to be analysed. The characteristics and performance of the individual components are described, and examples of measurements on Danish sediments are presented.
