This paper presents an innovative device for measuring artificial optic radiations (AOR). AOR are required to be measured in accordance with both Italian and European regulations. The traditional measurement methods do not provide a quantitative measurement of the energy affecting the retina and in particular the fovea. Hence, they are not suitable to assess the real risk to the eye. Furthermore traditional methods are not even able to measure the exposure time (in relation to the position of the head with respect to the source).
The device permits the acquisition of essential information about AOR source direction and position so as to obtain an evaluation of the relative impact on worker's everyday activity. The device acts as both a wearable personal dosimeter and an instantaneous radiance detector. The main components are: a colour light sensor mounted at the centre of a pair of safety goggles (placed on the same line of the worker's sight) used to determine AOR intensity; an inertial/position sensor used for measuring head position/movement, and lastly a video camera to localize emission sources and generate the background in augmented reality visualization. The device is connected by means of a thin, flexible cable to a datalogger and/or netbook? for recording data.
the experiments were carried out in order to evaluate AOR sources during work activity; the results obtained and duly processed are presented in the paper.
the aims are to achieve work place safety zoning so as to distinguish unsafe from safe areas, and not only specific dangerous areas, via analysis and integration of the overlapping pieces of information obtained with the proposed device.
本文介绍了一种用于测量人工光辐射（AOR）的创新设备。根据意大利和欧洲法规，需要对AOR进行测量。传统的测量方法无法对影响视网膜尤其是中央凹的能量进行定量测量。因此，它们不适用于评估对眼睛的实际风险。此外，传统方法甚至无法测量暴露时间（相对于头部相对于光源的位置）。
该设备能够获取有关AOR源方向和位置的基本信息，以便评估其对工人日常活动的相对影响。该设备兼具可穿戴个人剂量计和瞬时辐射探测器的功能。主要组件包括：一个安装在一副安全护目镜中心（位于工人视线同一线上）的彩色光传感器，用于确定AOR强度；一个用于测量头部位置/运动的惯性/位置传感器，以及最后一个用于定位发射源并在增强现实可视化中生成背景的摄像机。该设备通过一根细的柔性电缆连接到数据记录器和/或上网本以记录数据。
进行了实验以评估工作活动期间的AOR源；本文展示了所获得并经过适当处理的结果。
目标是通过分析和整合使用所提出的设备获得的重叠信息片段，实现工作场所安全分区，以便区分不安全区域和安全区域，而不仅仅是特定的危险区域。
