The PIMEX-method (PIcture-Mix-EXposure) involves measurement of exposure with a direct-reading instrument. The signal from the instrument is superimposed to the recording from a video camera to produce a video film which continuously shows the subject at work and how exposure varies. Application can be a physical factor such as vibration. We used this new method to study vibrations from hand held grinders. Using Brüel and Kjaer miniaturized accelerometer 4374 and vibration meter 2513 we measured vibrations at the grinders main and support handles. We studied different grinders at work on the metal surface as well as at idle speed. Workers posture such as arms in under-up position was evaluated. The PIMEX-method has been encouraging to show correlation between vibration exposure, work technique and different grinders.
PIMEX 方法（图片 - 混合 - 暴露）涉及使用直读仪器测量暴露情况。仪器发出的信号与摄像机的记录叠加，生成一部视频影片，该影片持续展示工作中的对象以及暴露情况如何变化。其应用可以是诸如振动之类的物理因素。我们使用这种新方法来研究手持式磨床产生的振动。我们使用布吕尔与克雅公司的小型加速度计 4374 和振动计 2513，在磨床的主手柄和支撑手柄处测量振动。我们研究了不同磨床在金属表面工作以及空转时的情况。对工人的姿势，如手臂处于上抬下方位置等进行了评估。PIMEX 方法已令人鼓舞地显示出振动暴露、工作技术和不同磨床之间的相关性。
