本文介绍了石英和长石光激发光测量装置的结构。用于刺激的光源是用于长石的红外二极管和用于石英和长石的来自卤素灯的绿色光（用滤光器系统获得）。该装置可以安装在Riso TL阅读器上，从而允许TL和OSL测量的组合。用该装置研究了TL和OSL信号之间的关系，石英样品在不同温度下退火后的发光，长石中潜发光信号的异常衰减。
The construction of a unit for measuring optically stimulated luminescence from quartz and fledspar is described. The light sources used for stimulation are infrared diodes for feldspar and green light from a halogen lamp (obtained with a system of filters) for both quartz and feldspar. The unit can be mounted on the Riso TL reader thus allowing combined TL and OSL measurements. The apparatus was used for studies of (1) the relation between TL and OSL signals, (2) the luminescence of quartz samples annealed at different temperatures and (3) anomalous fading of the latent luminescence signal in feldspar.
