...AR)对这些样品的细颗粒混合矿物进行了光释光(OSL)测年,测定结果表明:红外之后蓝光释光([post-IR] OSL)的年龄偏大,红外释光(IRSL)的年龄偏小或与蓝光释光(BLSL)的年龄基本一致,应用IRSL和BLSL信号测定的OSL年龄整体偏小可能与测定样品中长石矿物的异常衰退有关...

这样，安装在红外光焦点运动轨迹上的热释电敏感元件被红外光焦点不断扫描而产生自主采样的热释电信号。
So, the pyroelectric sensor that is located on the moving track of the infrared focus is scanned by the infrared focus signal continuously and generates the autonomous sampling pyroelectric signal.
被检测的热释电红外信号经过滤光镜片和摆动的凸透镜聚焦后，其红外光焦点同样也进行微幅摆动。
The detected pyroelectric infrared signal passes through an optical filter and is focused by the swinging convex lens and the infrared focus is also swinging slightly.
